James E. Davis — Chairman, President, CEO
Thanks, Shawn, and good morning everyone. We’re off to a strong start in 2023, our base business grew double-digits compared to prior year, driven by strong performance across physician and health system lab services. This morning we announced the acquisition of Haystack Oncology. Later in my remarks, I’ll describe how this transaction is aligned to the Molecular Genomics and Oncology strategy we shared last month at Investor Day and how it positions us well in the fast growing category of minimal residual disease testing.
Now turning to the first quarter, total revenues were $2.3 billion, total base business revenue grew 10%, supported by base business volume growth of nearly 8% and earnings per share were $1.78 on a reported basis and $2.04 on an adjusted basis.
Now let’s look at some of the highlights from the quarter. The strong volume growth we experienced in our base business across all customer types points to a continued return to care in the quarter. We saw a faster growth in a number of tests per requisition across a broad range of clinical test categories. This suggests, more people are returning to the healthcare system for routine care after delaying care during the pandemic. Health plan volumes also continued to grow faster than the overall business. This trend is directly related to our ongoing efforts to partner with health plans to actively steer patients to high-quality, lower-cost providers like Quest, thereby saving money for the health plans, employers and plan members.
During the first quarter, base revenues from health systems grew approximately 7% at Investor Day, we said this book of business would grow at about 5% to 6% CAGR and we’re having success across the board with new wins in our reference and professional lab services offerings. Some of these highlights include, in February, we announced that we’re helping Tower Health in Pennsylvania, manage its laboratory supply chain in addition to performance performing reference testing. Our Northern Light Health PLS relationship began to ramp up in the quarter. Northern Light is a large integrated health system in Maine, where we are providing services for all nine of its hospital labs and its cancer center. We also closed our acquisition of Northern Lights Outreach Lab assets.
Finally, we completed our strategic laboratory services acquisition with New York Presbyterian, with new test volume starting to flow into our Clifton, New Jersey laboratory earlier this month. This is the third outreach acquisition we completed in the last six months. As we enter the second quarter, our pipeline of new health system business remained strong, including many additional PLS opportunities.
Now I’d like to say a few words about our announcement this morning regarding our planned acquisition of Haystack Oncology. Haystack is an early-stage oncology company focused on minimal residual disease or MRD testing. Haystack has developed a highly sensitive liquid biopsy technology that can detect circulating DNA from residual or recurring tumor cells. The technology was licensed from Johns Hopkins, where it was developed by genomics and cancer pioneers. Most patients treated for cancer must be monitored for years following surgery and initial treatment. This is because there’s always the potential that some cancer was missed or may recur.
At Investor Day, we talked about Quest’s strong position in the mature cancer areas of screening and diagnosis, and that we will also play a leading role in therapy selection with our TSO 500 assay. Haystack’s liquid biopsy technology combined with our strengths and screening pathology and sequencing will now position us to play a leading role in the fast growing MRD category. We expect to focus initially on colorectal, breast and lung cancers and to start generating revenue next year.
We are also encouraged by other recent developments in advanced diagnostics. In the area of brain health, we saw strong growth, which we attribute largely to our Quest AD Detect Alzheimer’s blood test. This proprietary test launched last year helps us assess the risk of Alzheimer’s disease. We are now introducing additional tests to help us assess the inherited risk of Alzheimer’s and provide personalized recommendations to lower risk.
We also saw strong growth in our advanced cardiometabolic portfolio. Prenatal genetics, our blood-based tuberculosis screening and hepatitis B and C testing. We are encouraged by the CDC’s recent decision to recommend a onetime screening for hepatitis B.
In consumer health, we continue to add to our test menu with new services, including long COVID and menopause testing. We also generated strong year-over-year volume growth in allergy and general health testing as consumers utilize our offerings as a complement to the care provided by their physician. In the coming months, we plan to launch a new consumer genetics panel as well.
Turning to Invigorate, we are well on our way towards achieving our 3% annual productivity savings target. Here are some recent examples among the many contributors. We are improving the efficiency of our patient services network. In some cases, we’re closing smaller draw sites and adding staff to larger higher volume locations. At the same time, we’re making it easier for walk-ins to register and be seen through our schedule at check-in service. We are adding new features to the pre-registration process, which improves both collections and patient convenience.
During the pandemic, we relied heavily on third-party logistics to supplement our own teams’ collections of COVID-19 tests and other specimens. COVID-19 volumes have declined and the labor market eases, we are reducing our dependence on these vendors, which will generate savings for our logistics operations. Finally, we’re continuing to enhance our labor staffing models across our lab network to reflect post-pandemic total volumes and drive productivity. As we have said before, we continue to closely manage the cost of our corporate and support functions. The actions we’ve taken will start to help margins beginning in the second quarter.
Finally, I’d like to give you an update on where we are with medicare clinical lab fee schedule cuts. As you know, PAMA cuts were suspended for 2023, We strongly support the recent bipartisan reintroduction of the legislation in Congress to fix PAMA through the saving access to Laboratory Services Act or SALSA. We are working with our trade association, and driving advocacy for SALSA through a campaign to stop lab cuts, aimed at Congressional outreach and the importance of lab services.
Now. I will turn it over to Sam, to provide more details on our performance and our updated 2023 guidance, Sam?
Sam Samad — EVP, CFO
Thanks, Jim. In the first quarter. Consolidated revenues were $2.3 billion, down 10.7% versus the prior year. Base business revenues grew 10% to $2.1 billion, While COVID-19 testing revenues declined approximately 80% to $119 million. Revenues for Diagnostic Information Services declined 11.1% compared to the prior year, reflecting lower revenue from COVID-19 testing services versus the first quarter of 2022, partially offset by strong growth in our base business.
Total volume measured by the number of requisitions declined 3.8%, versus the prior year, with acquisitions contributing 10 basis points to total volume. In the quarter, total base testing volumes grew 7.9% versus the prior year. Recall, our base testing volumes in the first quarter of last year were negatively impacted by surge in COVID-19 cases due to the spread of the Omicron variant. If we normalize for the impact of the easier comps due to the Omicron surge in Q1, ’22, we estimate base volume growth at approximately 4%.
COVID-19 testing volumes continued to decline during the first quarter. We resulted approximately 1.3 million molecular tests in the quarter, down approximately 5 million tests versus Q1, 2022. Revenue per requisition declined 7.7% versus the prior year, driven by lower COVID-19 molecular volume. Base business revenue per req was up 0.3% due primarily to more tests per requisition, as well as positive payer and test mix. Unit price was roughly flat, which was consistent with our expectations.
Reported operating income in the first quarter was $305 million or 13.1% of revenues compared to $513 million or 19.7% of revenues last year. On an adjusted basis, operating income was $350 million or 15% of revenues compared to $554 million or 21.2 percent of revenues last year. The year-over-year decline in adjusted operating income is related primarily to lower COVID-19 testing revenues partially offset by growth in the base business.
Reported EPS was $1.78 in the quarter, compared to $2.92 a year ago. Adjusted EPS was $2.04 compared to $3.22 last year. Cash from operations was $94 million in the first quarter versus $480 million in the prior year period. The decline in operating cash flow was primarily related to lower operating income and an additional payroll cycle during the quarter versus the prior year.
Now turning to our updated full-year 2023 guidance. Revenues are now expected to be between $8.93 billion and $9.08 billion. Base business revenues are expected to be between $8.78 billion and $8.8 billion. COVID-19 testing revenues are expected to be between $150 million and $200 million. Reported EPS expected to be in a range of $7.52 to $8.02, and adjusted EPS to be in a range of $8.45 to $8.95. Cash from operations is expected to be at least $1.3 billion and capital expenditures are expected to be approximately $400 million.
Here are some things to consider for the remainder of the year. We have lowered our COVID-19 revenue guidance, which now assumes very modest COVID-19 revenue, following the end-of-the public health emergency in May. COVID-19 molecular volumes have declined faster than we expected over the last several weeks, and we now expect minimal volume contribution from the retail channel post-PHE. We have raised our base business revenue guidance to reflect stronger base volume trends and the recent close of the New York Presbyterian transaction.
We expect the Haystack Oncology transaction to close in the second quarter. Our updated EPS guidance reflects the expected dilution from this transaction in 2023. We expect this deal to be modestly dilutive to EPS over the next three years and accretive to earnings by 2026. We anticipate Haystack Oncology to begin contributing revenue in 2024 and to have a positive ROIC by the end of 2025.
With that. I will now turn it back to Jim.
James E. Davis — Chairman, President, CEO
Thanks, Sam. To summarize, we’re off to a strong start in 2023 and our base business grew double digits compared to prior year. We are excited about our announced acquisition of Haystack Oncology. With Haystack, we expect to build on our strengths and cancer screening and diagnosis to play a leading role in the higher-growth areas of MRD detection. And finally, we’re well on our way toward generating our targeted 30% Invigorate savings and productivity improvements.
Now we’d be happy to take your questions, operator?
Questions and Answers:
Operator
Thank you. We will now open it up to questions. [Operator Instructions] Our first question comes from Ann Hynes of Mizuho Securities. Your line is open.
Ann Hynes — Mizoho Securities — Analyst
Great, thank you. My question is focused on the base volume growth, which was strong. And in your commentary, you talked about health plans that you’re gaining more market share there, and you are winning more market share, I think you said with reference labs. Maybe can you give us more detail on that, is it existing healthcare partners? Do you have a new healthcare partner? Is your relationship with existing partners may be changing? And I’m just trying to figure out how much is a return to normal versus maybe actual market share you could be gaining. Thanks.
Sam Samad — EVP, CFO
Yeah, hey, thanks, Ann, and good morning. So our growth in the quarter, again 10% base revenue growth was strong across all channels, our physicians segment and our health systems segment.
Now within the health systems segment, we look at our reference business and our PLS business. Our reference business was powered by growth from existing accounts as well as we had several new big wins that you actually win those deals in previous quarters, but the start-up was in the first quarter.
On the PLS side, or Professional Lab Services, our growth at existing sites same-store sales was very strong, but we also added, as you know, a couple of new PLS sites both in the foruth quarter, that we’re ramping-up and in the first quarter. Those were Lee Health in Florida, as I mentioned in the script Tower Health and then Northern Light in Maine, a multi-hospital health system up in Northern Maine, continued to ramp up in the first quarter. So broad-based growth physician business was very strong, health systems business strong, and PLS certainly helped the average growth rate in the quarter.
Operator
Thank you. Our next question comes from Patrick Donnelly of Citigroup. Your line is open.
Patrick Donnelly — Citigroup — Analyst
Hey guys, thanks for taking the questions. This might be one for Sam, just on the margin side. As we look at the base margins going back at our COVID shaken out somewhere around 13%. I guess when you look at the go-forward, you’ve been getting into next year kind of approaching that 17% type number. Can you just talk about — I don’t know if it’s a bridge or just the — it’s just the progression towards that, how you work your way towards that as particularly as COVID continues to come out-of-the model a little bit. I’m just want to focus on that base margin piece and how we think about the step-up there.
Sam Samad — EVP, CFO
Sure, Patrick. And good morning, thanks for the question. So listen, we had 15% operating margins in Q1. I’ll talk about some of the drivers in terms of — to your question looking forward, and how we get to that, approximately 17% that we guided to on Investor Day. And we’re still committed to that approximately 70% number that we guided for 2023.
So here are some key drivers. First of all, Q1 margins came in on the base business, strong and overall, as expected, we had a negative impact from COVID revenues coming down more precipitously than expected, but also the mix on COVID. We saw more testing done at the PLS sites than at other sites which are lower cost for us.
But in terms of Q1 came in as expected. As we look forward, we start to see a few things help margins. First of all, keep in mind, Q1 is usually our weakest quarter as well. But as we look forward, do you expect Invigorate savings to — or productivity improvements to ramp up. And that has already started, but will ramp up over the course of the year. We said our SG&A reductions of approximately $100 million will really take effect more so in Q2 onwards, and so that will help margins going forward as well.
We’re seeing, as I said, good strong base business growth and volume that’s going to help us. We’re seeing a good tailwind from pricing. Our pricing environment is the best that it’s ever been. We’re seeing modest benefit from pricing this year, compared to the 50 basis points headwind that we saw last year and before that, we used to have even more headwinds than that. So all of those factors, as you look forward, in terms of productivity, in terms of SG&A improvement, in terms of volume growth give us confidence about getting to that 70%.
James E. Davis — Chairman, President, CEO
Yeah, the last thing I’d add, Patrick, is our test mix in the quarter was strong. Our investments in advanced diagnostics continue to pay off. We saw — as I said in the script, really nice growth in advanced cardiometabolic testing prenatal genetics, hep B, hep C. So these are all margin-accretive types of tests. So, we feel good about that.
Operator
Thank you. Our next question comes from Brian Tanquilut of Jefferies. Your line is open.
Brian Tanquilut — Jefferies — Analyst
Hey, good morning, guys. Congrats on a quarter. A question for you guys, as I think about the callout you made on tests per req being up in the quarter. Maybe, if you can give us some color on what is driving that and how you think that will progress going forward, I guess, test per req. Thank you.
James E. Davis — Chairman, President, CEO
So, I think there is evidence of a strong return to care. So. I just said that our advanced testing portfolio was certainly up in the quarter. We also saw strong growth in routine testing, routine cardiometabolic lipid panels, chemistry panels, and things like that.
Generally, general health and well — general health and wellness visit has high tests per req, because you’re testing across the entire human body. So. I think the tests per req were really powered by that.
Operator
Thank you. Our next question comes from Elizabeth Anderson, Evercore ISI. Your line is open.
Elizabeth Anderson — Evercore ISI — Analyst
Hi guys, thanks so much for the question. I was wondering if you could talk more about your visibility into pricing and contract renewals, particularly with payers this year. How far long are you at the renewals and sort of what incrementally have you been seeing or is it sort of similar to what you’ve called out current trends? Thank you.
James E. Davis — Chairman, President, CEO
Sure. So, I think as everybody knows, in general, our contracts with commercial payers average, three to five years. So on average every year we’re going to renegotiate about 25% of our health plan contracts. We’re now a third of the way through the year and we’ve progressed nicely on two of the contracts that have been renewed. We have a few more to do throughout the rest of the year.
So what I would tell you is, look, we have a great value story. Consistently, we’re able to move requisitions from high-priced institutions, health systems in out-of-network labs into Quest Diagnostics. And we tried to negotiate incentives for doing that. And when we do that work, we get paid incremental value. So these value-based contracts are on the rise. And we certainly make the case around inflation and things like that, but as I’ve said in the past, we don’t lead with that. We lead with the fact that we offer great value and we want to get paid for that value. So negotiations are going well.
We said in the quarter, that price was flat, which we haven’t been able to say in a long time. Q4 we are down 50 basis points, Q1 we’re flat, so we continue to make improvement, and expect to make improvement throughout the rest of the year.
Elizabeth Anderson — Evercore ISI — Analyst
Thanks so much.
Operator
Thank you. Our next question comes from Kevin Caliendo of UBS. Your line is open.
Kevin Caliendo — UBS — Analyst
Hi, thanks for taking my question. Congrats on the Haystack acquisition. Can you maybe talk through the process there? Why now, why this company talk through any — I know there are some regulatory and commercial milestones this company has coming up. And also maybe just talk through how we should think about the dilution in terms of modeling it. And where that would show up through the P&L?
James E. Davis — Chairman, President, CEO
Yeah, so let me just have Sam address the dilution first and I’ll come back and talk about why Haystack and why now. Sam?
Sam Samad — EVP, CFO
Yeah, so — Kevin, first of all, thanks for the question. So we said, this deal will be modestly dilutive this year and modestly dilutive for the next three years and will be actually accretive for us in terms of earnings in 2026. We haven’t shared exactly how dilutive it is for 2023, but let me give you a couple of maybe nuggets or qualitative directional comments.
First of all, in terms of our overall guidance. As you saw, we kept our guidance midpoint the same. We narrowed the guidance by $0.10 on EPS, so I am referring here, specifically to adjusted EPS. And the drivers of that were improved base business which is taking us higher– lower COVID which is going the other way and some modest dilution from the Haystack acquisition. But all-in-all, if you put all those together, we’re still at the midpoint of the adjusted EPS guidance that we were last quarter.
In terms of going forward, the annualized EPS dilution from Haystack. Next year is actually less than what we expect to see this year. So it starts to improve. Next year is the peak dilution for the deal and in 25, the dilution is lower, so it’s actually a year-over-year EPS improvement. And then in ’26, as I said, it’s accretive for us from an EPS perspective. ROIC wise, as I said, it turns positive by the end of ’25 and we expect it to have — it definitely clears our hurdle for ROIC expectations in the next five years.
James E. Davis — Chairman, President, CEO
Yeah. So, Kevin, let me talk a little bit now about why Haystack and why now? So first, as we talked about at Investor Day, when we are looking to close a capability gap if you will in our portfolio, the first thing we do is, we reach out to our IVD partners. And over the last several years, we’ve had deep discussions. We know what their roadmaps are and we didn’t think that was a pathway to follow to get into this space, at least in the next several years, let’s just say.
Over the last three years, we’ve had many discussions with many of the players in the MRD space. We got to know Haystack over the last year, we think they have the lowest limit of detection of any MRD assay out there. In terms of just raw numbers, they can detect one part per million, meaning you have one million floating cells as they die, they release DNA, the fragments of DNA. And there’s a lot of DNA in your bloodstream and these guys with this assay can find one fragment of cancer DNA per one million parts. That is an incredibly low limits of detection.
The sensitivity of the assay. And landmark is very very high, 80% to 90%. And so we think it’s a best-in-class assay. The work they’ve done on some of their preliminary trials, 450 patients across 23 Australian centers, I’d refer you to the New England Journal of Medicine article in June of 2022. So we think it’s the right assay, the right time. As you know, CMS is reimbursing for these assays. And we think we can scale it. We think we can drive further commercial reimbursement.
The last thing. I would say is look it is a tumor-informed assay. And when you’re looking for a needle in a Haystack, hence, their name. When you’re looking for a needle in a Haystack, you actually want to know what the needle looks like. And hence, we believe that the tumor-informed assay is a much stronger assay than an uninformed assay. One other thing just to wrap up on the financials. Kevin, back to your question, around dilution. I do want to mention for the longer term we are committed to the Investor Day guidance that we gave around long-range guidance, which said mid-single-digit revenue growth and high single-digit EPS growth. The Haystack acquisition actually modestly improved on that as well. So, I just wanted to provide this for the long-term guidance, given that we just shared with an Investor Day talked too long ago.
Operator
Thank you. Our next question comes from Jack Meehan of Nephron Research. Your line is open.
Jack Meehan — Nephron Research — Analyst
Thank you, good morning. Wanted to stick with the Haystack deal, very interesting pretax pricing is pretty reasonable than other deals in the space. Had a few more questions for you. First is, in terms of coverage. Just wanted to confirm, I assume the plan to go through mold tests there. Then number two, do you think reimbursement looks similar to other MRD test on the market? And then finally, can you just comment, are there any royalties attached to the deal? Thank you.
Sam Samad — EVP, CFO
Yeah. So yes, Jack. The first, thanks for the question. Yes, on mold test, absolutely plan to go that route. Look, what we have to do is. Is finished. The commercialization of the assay. We’ll be doing that for the rest of this year. We plan on bringing the assay up in one of our large oncology testing facilities. As you know, there is limited coverage for Medicare and Medicare Advantage patients as dictated by CMS. Two companies have coverage for that today. I would also tell you, there’s a handful of Blues — company with the Blues plans that are reimbursing for the test.
So similar to NIPT, remember NIPT started out very high-risk women, very limited coverage. And we as well as some other industry members drove that throughout the commercial payers. And that test is wide open to women today. So that’s our plan.
On the royalty question. Look, as we mentioned in the comments, the — some of the original IP came out of John Hopkins. I’m not going to disclose our royalty payments, but as you can imagine there is intellectual property that comes with this and there’s modest royalties that will come with it.
Shawn Bevec — VP, Investor Relations
Operator, next question.
Operator
Thank you. Our next question comes from Erin Wright of Morgan Stanley. Your line is open.
Erin Wright — Morgan Stanley — Analyst
Great, thanks. Two-part question. Just first on basic routine testing, where are we now relative to pre-COVID baseline levels fully back to normal here? And then on capital deployment, I understand there’s a balance of capital deployment, dedicated to the innovation assets like Haystack. But how rich is the pipeline now for the tuck-in deals around hospitals, their local players, and. And have you seen any changes in the urgency around those types of deals. Thanks.
James E. Davis — Chairman, President, CEO
Yeah, so our routine testing levels our above pre-COVID levels, whether you look at our volume versus all of 2019, are you look at our volume purchases the first two months of 2020 were substantially above that. So, the recovery is no longer really even a topic of discussion for us.
In terms of the funnel of opportunities on the health system side, namely outreach deals is stronger than ever. And I think now that COVID is behind us, the deal completion will start to accelerate. So we feel good about what’s in the funnel. They generally take a while to negotiate. We got to get a lot of people on-board, pathologists onboard, referring physicians. But once you get them onboard, it could move quickly.
Operator
Thank you. Our next question comes from Pito Chickering of Deutsche Bank. Your line is open.
Kieran Ryan — Deutsche Bank — Analyst
Hi, there. You got Kieran Ryan on here, for Pito. Thanks for keeping the question. Just going back to margins. I was just wondering if you could talk a little bit about FTE wage inflation, hiring. and turnover, how that ran in 1Q compared to what you’re seeing in the second half of 2022? And then just kind of how that fits into getting back to that 17% margin next year.
Sam Samad — EVP, CFO
Yeah. So the guidance we gave for the year, we said our wage inflation will be in the 3% to 4% range. No surprises there. We still feel good about that overall guidance that we set for the year.
Our turnover rates have improved from Q1 of last year. Sequentially for most job categories, it improved from Q4 to Q1, and we continue to see the trend back, towards a normalized attrition rate. When I say normalized for the pre-COVID levels. It is not yet back to those levels, unlike volume. But it is trending in the right direction and we feel good about where our wage inflation was in the first quarter and for the year.
James E. Davis — Chairman, President, CEO
Yeah, and I’ll just mention a couple of things real quick. I mean productivity in terms of the Invigorate actions that we have, helps also offset that, which is how we get to the margin target that we have. I think you mentioned Kieran, that the 17% next year. Actually, our guidance is to get to approximately 17% this year in terms of operating margins, so I just want to be clear on that.
Operator
Thank you. Our next question comes from Andrew Brackmann of William Blair. Your line is open.
Andrew Brackmann — William Blair — Analyst
Hi guys, good morning. Thanks for taking the question. Maybe just to go back to Haystack for a minute and appreciate all the commentary today on that. Can you maybe just sort of talk about any expectations for a halo effect that this can create for you guys commercially? And. I guess just as you sort of think about that, how are you thinking about any changes to the commercial strategy just between calling on pathologists and then the oncologists here? Thanks.
James E. Davis — Chairman, President, CEO
Yeah, so good question. Absolutely a halo effect. Remember at Investor Day, we said in 2022, ex-COVID, we had $8.4 billion in revenue, and of that $8.4 billion, $1 billion of that is in the cancer space. And we said about half of that or $0.5 billion is in the screening space routine screening PSA. Pap smears, HPV, some common cancer markers. But we then said that the other $0.5 billion is anatomical pathology. So we have the specimen — and once we have that specimen, it’s only logical for the medical oncologists to start to once it is declared cancer. The next question, post-surgery is, is there still cancer cells in this human being? Or the next question — if the answer to that is yes, and then there’s therapy. The next question is, did the therapy work,? Do we still see remnants of DNA from the tumor?
So we think this absolutely fits in to our overall cancer strategy and Quest Diagnostics today. In particular, again there is a halo effect. We will own the block we will own the specimen and doing the testing on that football treatment monitoring as well as treatment selection. we think is just a natural.
Now from a commercial standpoint, we have a pretty mature oncology distribution today that calls on pathologists and medical oncologists, And yes, we are absolutely going to strengthen that team as we finish the commercialization of this assay and to have a more robust channel calling into the medical oncology space. So good question. Thanks.
Operator
Our next question comes from A.J. Rice of Credit Suisse.. Your line is open.
A.J. Rice — Credit Suisse — Analyst
Thanks. Hi, everybody. Maybe two quick ones here if. I could slip them in. The strong rebound in the base business volume. We’ve talked for a while about the fact into New York region had not come back as quickly as other regions. Did you see any outsized performance there, that’s contributing to the strong base business, or was the strength pretty much across the board geographically?
And then, you didn’t do anything on the buyback front this quarter. I know you’ve got Haystack now and you’ve got hospital deals. I wondered what your thought about additional share repurchases as we progressed through the year.
James E. Davis — Chairman, President, CEO
Yeah, thanks, AJ. So on your first question, I’ll let Sam take the second part. Again, 10% revenue growth on the base business in the quarter, 8% volume growth, I mentioned that health systems was 7%, so our physician book of business actually grew higher than that, if you do that math. And the answer is, we saw strong growth across all of our regions. Did the Northeast grow at a faster rate, slightly faster rate, yes. So we saw maybe a bit of a rebound there.
But look, our comparisons now in the Northeast region are with 2022. There has been population shifts that — some of that population is just not going to come back to the Northeast. Now, we see continued stronger growth in the Southeast, and that very much could represent some population shift that we’re seeing in the country.
The last thing I’d mention, although it didn’t influence our Q1 numbers, we did mention the startup of our Newyork-Presbyterian outreach deal that’s going well. It’s going to be a strong contributor to growth in the East region and will be a strong contributor to our overall growth for the rest of the year. So Sam, do you want to take that?
Sam Samad — EVP, CFO
Yeah. And, A.J. On the buyback, so what’s assumed in our guidance in terms of adjusted EPS is that we will offset equity dilution in terms of share buybacks. So we’ll do enough to offset equity dilution. We are still committed to returning the majority of our free cash flow to shareholders through dividends and buybacks. So that’s still our commitment. We communicated it on our Investor Day. We’re obviously still committed to it.
But we also said that we’re going to scale share buybacks up and down depending on also the M&A pipeline and the impact that might have on growth and driving our strategy and also our long-term growth. We had — in the quarter, we talked about or at least recently, we talked about New York-Presbyterian and the fact that, that’s a $275 million capital deployment. We talked about now today, Haystack, and that’s an additional capital deployment of $300 million. So we’ve had good progress here on the M&A front. So that’s also why we didn’t do any share buybacks in Q1.

Hey, good morning. I wanted to ask about the consumer initiated testing business in terms of contribution if you’re allowed to say how much contribution you saw in one in terms of sales and how much of an impact is made on the margins? Just curious if that’s something I should look out for in terms of the margin progression here. Thank you.
James E. Davis — Chairman, President, CEO
Yeah. So we are really happy with our consumer-initiated testing performance in the quarter. It showed nice growth from — progressive growth from Q4. And so I’m going to talk about the growth. And COVID obviously declined in that segment of our business as well. The majority of our CIT business now is our routine-based business.
We saw a nice progression from Q4 to Q1. We are happy with that. We saw nice progression Q1 to Q1, really nice progression there. We continue to be excited about a couple of growth categories within CIT. Number one, you’ve probably read allergy season has really taken off and taken off early. So seeing some nice growth there. Just our general health and wellness offering in CIT was really strong in the quarter.
And we surveyed some of those general health and wellness customers and found some interesting things. One of the main reasons they’re coming to Quest and paying out of pocket is because patients were — consumers patients were having a hard time getting in to see their physicians. We’re hearing about three-month delays to get to see their doctor. So rather than wait to see their doctor and get their lab testing, they just come in because they want to know.
And then finally, I’d say our STD category continues to exhibit very strong growth. The CDC just declared again several types of STDs [gonorrhea syphilis at epidemic levels. They also indicated that 50% of all new cases that they’re seeing across the country are aged 15 to 24. And that’s a segment that wants to remain anonymous and just pay out of pocket for lots of reasons.
Finally, as we’ve said about margins, our CIT business is going to be less dilutive this year than it was last year. And I think you can assume that each quarter through the year.
Sam Samad — EVP, CFO
Yeah. So John, just to add to that, it is dilutive in Q1 to margins. But as Jim said, it’s going to improve throughout the year. So that’s another aspect of why our margins overall improve, although this one is more modest.
Shawn Bevec — VP, Investor Relations
Operator, is there any more questions?
James E. Davis — Chairman, President, CEO
All right. Well, I want to thank everyone for joining today, some really exciting news here. But let me just summarize, look, we’re off to a really strong start here in 2023. Our base business performed stronger than expected, stronger than we expected in the quarter. We feel really, really good about that. And it’s certainly offsetting some of the COVID decline that we saw in the quarter.
Second, hopefully, you can tell, we’re really excited about the Haystack Oncology. We think that technology is the right technology. But more importantly, it’s the right team. We’re really impressed with the team that will join Quest Diagnostics. And as you know, in these types of acquisitions, it’s not just investing in the technology and really investing in a group of people and a team, and we feel really, really good about that. We feel great about the MRD space and we believe it’s starting to mature from both a physician ordering perspective as well as from a reimbursement perspective.
And then finally, we’re well on our way to generating the Invigorate savings that are needed to offset wage inflation, and we feel good about the progress we’re making there.
So again, thanks for joining in, and we look forward to seeing you out on the road over the next few months and joining us at our next earnings call in July. So thanks for joining, and have a great day.
