This page compares WHOOP Advanced Labs and Function Health on price, panel depth, and what each does with your results. Every price and product claim below was checked against the companies' own published pages on 4 September 2026 and linked to its source. Where a figure comes from trade press rather than a vendor page, it says so.
Who publishes this page, and why that matters
This page is published by Merios, which makes blood-test tracking software that combines lab results with wearable data. Merios competes with both products reviewed here, and most directly with WHOOP Advanced Labs, because combining bloodwork with continuous wearable data is exactly what Merios sells. You should read this page knowing that.
Because of that conflict, three rules govern this page. Merios is not its subject and is never ranked first on it. Merios appears only as a clearly labelled third column in the tables, plus one short section and one describing the cases where you should not use it. And there are no affiliate links anywhere here — no referral codes, no tracked links, no commission on anything you buy from either company. We make nothing if you buy WHOOP Advanced Labs or a Function Health membership.
For the other side of this category, our comparison of Function Health against Superpower covers the two lab-only memberships head to head.
The 30-second answer
- Choose WHOOP Advanced Labs if you already wear a WHOOP. Your labs land in the same app as your recovery, sleep and strain history, and nothing else on this page can do that. The multi-test tiers also get cheap per draw.
- Choose Function Health if you want the widest single panel, clinician review stated as non-optional, and no hardware in your life. It measures more in one sitting than WHOOP does, for six dollars more a year.
What changed in 2026 is that WHOOP dropped the membership gate. That makes Advanced Labs buyable by anyone — and a weaker buy for anyone who does not wear the strap, because the integration is the product.
How we picked
These are the criteria, stated before the verdict, in the order we weighted them:
- Total first-year cost, including any subscription the product requires or strongly implies, verified against the vendor's own pages.
- Biomarkers per draw, not per year. Annual totals hide whether you get breadth in one sitting or the same panel repeated.
- Price per biomarker, computed by us. Neither company publishes it.
- What each one measures, and whether the catalogue number is one you can actually buy.
- Who reviews your results — a clinician, an algorithm, or a report template.
- Draw logistics, including where you can and cannot get drawn.
- Data export, because both hold years of your history.
We did not accept either company's description of the other, and we treated August 2026 press coverage as secondary to the vendors' own live pages wherever the two could be checked against each other.

| WHOOP Galleri test | Multi-cancer early detection | $799 | shop.whoop.com/us/en/advanced-labs/panels |
| WHOOP wearable membership | One $199 / Peak $239 / Life $359, hardware included | $199 to $359 per year | whoop.com/us/en/membership |
| Function Health | 160+ lab tests annually, 2 draws | $365 per year | functionhealth.com/pricing |
| Merios (publisher of this page) | Software only, no lab draw | Free Basic, $14.99 per month Pro, roughly $180 per year | merios.life |
The multi-test tier prices are the one set of numbers we could not confirm on a vendor page. WHOOP's panels page shows $199 and the line "as low as $150 per test when you select 4+ tests," but does not break out the tiers without entering checkout. The $349, $599 and $899 figures come from trade press covering the 18 August 2026 announcement, and are arithmetically consistent with WHOOP's own claim — $599 divided by four is $149.75. That is why we publish them, and why we label them anyway.
Since 18 August 2026 no WHOOP membership is required. WHOOP's product pages now say "No subscription or wearable required." That is why most existing comparisons of these two products are wrong. Merios includes no blood draw at any price, which is why its row is not comparable and why there is a section below on when it is the wrong purchase.
What the first year actually costs
The sticker prices are close. The realistic totals are not, and it turns on one question: do you already wear a WHOOP? Every figure below is carried from the sourced table above, verified 4 September 2026.
| Scenario | First-year total | What you get |
|---|---|---|
| Function Health | $365 | 160+ lab tests across 2 draws, clinician review, no hardware |
| WHOOP Advanced Labs only, no strap | $349 | 150 measurements across 2 draws of 75 markers, clinician report |
| WHOOP Advanced Labs plus WHOOP One | $548 | The above, plus the wearable and the integration |
| WHOOP Advanced Labs plus WHOOP Life | $708 | The above, on the WHOOP MG hardware |
| Merios (publisher), labs sourced separately | ~$180 plus your lab costs | Software only |
WHOOP's two-test tier without a strap costs $16 less than Function Health and measures fewer distinct markers. With the entry-level membership it costs $183 more, and that $183 buys a wearable and the pipeline connecting it to your labs. That is the actual decision.
Price per biomarker
This is our own computation, dividing the price by the marketed count. Every price is carried from the sourced table above, verified 4 September 2026.
| Product | Marketed count | Price | Price per marketed unit |
|---|---|---|---|
| WHOOP Basic Health Panel | 53, one draw | $69 | $1.30 |
| WHOOP Comprehensive, 1 test | 75, one draw | $199 | $2.65 |
| WHOOP Comprehensive, 2 tests | 150, two draws of 75 | $349 | $2.33 |
| WHOOP Comprehensive, 4 tests | 300, four draws of 75 | $599 | $2.00 |
| Function Health | 160+ across two draws | $365 | $2.28 |
| Merios (publisher) | Not applicable, no lab draw | ~$180 | Not comparable |
At the tiers most people buy, these two land within five cents of each other — $2.33 against $2.28. Price per biomarker does not separate them.
The units are not equivalent, though. Function's 160+ is 100+ tests at the annual visit and 60+ three to six months later, so the first draw is genuinely broad. WHOOP's 150 is the same 75 markers measured twice — a second data point on markers you already had, valuable for trend but not for breadth.
Read that way, the comparison inverts depending on what you want. For breadth in one sitting, Function measures roughly a third more distinct things. For trend density, WHOOP at four or six tests a year sells something Function does not: the same panel every quarter at $2.00 per measurement. Our guide to biomarkers worth tracking for longevity and the piece on how often you should get bloodwork are more useful here than either catalogue.
What each one actually measures
WHOOP advertises 122+ distinct biomarkers, and that number is not buyable as a single product — it is the union of every panel in the catalogue. The Comprehensive Health Panel, the one in the subscription, is 75. The five specialized panels (Heart 81, Performance 90, Women's 81, Metabolic 78, Men's 77) are $299 each on top and overlap heavily with the comprehensive panel rather than adding cleanly to it. Function, for its part, publishes no reconciliation of what counts as a "lab test."
At the category level both cover the same core: complete blood count, comprehensive metabolic panel, lipids, thyroid, sex hormones, inflammatory markers, iron studies and the common vitamins. Neither is missing anything a general physician would order; the differences are at the edges and in the add-ons.
The Galleri addition, and what it does and does not establish
On 18 August 2026, WHOOP added GRAIL's Galleri multi-cancer early detection test to Advanced Labs, at $799. It is the most consequential thing either company sells and the easiest to oversell, so it is worth being precise.
On price: WHOOP lists Galleri at $799, HSA/FSA eligible, ordered by a licensed physician with no separate visit, drawn at Quest, results in the WHOOP app in about two weeks. GRAIL's own consumer price is $949, so WHOOP's is a genuine discount to buying direct. Function Health also offers Galleri as a member add-on but does not publish the price on its pricing page or FAQ, and we could not verify it. We will not guess.
What it is, in GRAIL's own words on its patient FAQ: the test "has not been cleared or approved by the Food and Drug Administration," it was "developed — and its performance characteristics were determined — by GRAIL," and it "is intended to be used in addition to — and not replace — other cancer screening tests." GRAIL reports a 0.4% false positive rate, a positive predictive value of 62%, and that nearly 99% of people aged 50 to 79 receive a "No Cancer Signal Detected" result.
What the evidence shows: the NHS-Galleri trial, the largest randomized test of the technology, enrolled 142,942 asymptomatic adults aged 50 to 77 and reported full results at ASCO in 2026. It missed its primary endpoint — three annual rounds added to standard screening produced no statistically significant reduction in combined stage III and stage IV diagnoses for the twelve prespecified cancers (hazard ratio 1.03, 95% CI 0.92 to 1.14). Secondary analyses were more favourable, with a reported 14% reduction in stage IV diagnoses and a 16% increase in stage I and II detection, and GRAIL has filed a premarket approval application with the FDA. Those secondary findings are hypothesis-generating, not proof.
The American Cancer Society's position is that "there are no clinical practice guidelines or official recommendations for using MCDs in the United States," and that these tests "do not replace current screening tests" such as mammography, cervical screening, colonoscopy, PSA testing and low-dose CT.
The practical takeaway: a negative Galleri result does not mean you do not have cancer, and is not a reason to skip a colonoscopy or a mammogram. A positive result starts a diagnostic workup with roughly a 62% chance of finding cancer and a 38% chance of a false alarm. It is a legitimate product with real published data behind it, sold into a category with no guideline support — and it should not decide this comparison either way.
Who reviews your results, and what happens next
| WHOOP Advanced Labs | Function Health | Merios (publisher) | |
|---|---|---|---|
| Who orders the test | Licensed physician, no separate visit | Licensed provider through Function | Nobody — you bring existing results |
| Review model | "A clinician reviews your biomarker results and creates a personalized Action Plan" | "Clinicians review every result and flag issues" | Software only, no clinician, no medical review |
| Output | Clinical Report plus Action Plan, in the WHOOP app | Per-marker explanations written by physicians | Algorithmic, referenced to published ranges |
| Source | shop.whoop.com | functionhealth.com/faq | Merios product |
Both state clinician review as included rather than optional, which is more than several competitors manage. WHOOP's distinctive addition is an Action Plan tied to your wearable baseline: the report can reference your own resting heart rate and sleep history rather than a population average. Merios reviews nothing — it is analysis software, not a medical service.
Draw logistics, export, and cancellation
| WHOOP Advanced Labs | Function Health | Merios (publisher) | |
|---|---|---|---|
| Draws per year | 1, 2, 4 or 6, depending on tier | 2, plus on-demand at extra cost | None — you bring existing results |
| Where | 2,000+ Quest locations, booked in the WHOOP app | 2,000+ locations nationwide | Any lab, anywhere |
| Not available in | Arizona, Hawaii, Wyoming, North Dakota, South Dakota; tests may be completed out of state | Not published as a restriction | Not applicable |
| Turnaround | Typically 7 to 10 business days | Not published as a guarantee | Immediate on upload |
| HSA/FSA | Marked eligible on every panel | Stated eligible, itemized receipt provided | Software, generally not eligible |
| Data export | CSV export of wearable data and a developer API; lab-result export not documented | PDF download to share with a provider; no CSV advertised | Export supported |
| Cancellation | Subscription tiers cancellable; one-time panels are one-time | "Cancel and rejoin at any time"; no pauses | Monthly, cancel anytime |
| Refunds | Not published | "Function does not offer refunds for prior payments" | Monthly billing, no annual prepayment |
Two lines deserve attention. The state restrictions are real: five states cannot be drawn locally through WHOOP, and while tests may be completed out of state, that is a real obstacle if you live in one. And neither company gives you your lab values in a structured format. WHOOP exports wearable data as CSV and runs a developer platform but does not document lab-result export; Function gives you a PDF. If you intend to track a marker across a decade and across providers, that constrains both.
The real trade-off
WHOOP's case is that a blood marker means something different when you can see what your body was doing around the draw. A cortisol reading next to three months of sleep data, or a lipid panel next to your actual training load, is more interpretable than the same number in isolation. That is a real argument, and it is the argument Merios makes too, which is why we will not pretend it is weak. Our explainers on heart rate variability, HRV by age and deep sleep cover why continuous data adds signal.
The cost of that case is the ecosystem. The integration works only inside the WHOOP app, only with WHOOP hardware, and only while you keep paying — WHOOP devices stop functioning when the membership lapses. Switch to an Oura ring or an Apple Watch in two years and the labs stay in an app you no longer open. WHOOP's own metrics are not beyond question either: consumer VO2 max estimates vary more than the marketing suggests, whichever brand you wear.
Function's case is the opposite. Lab-only, platform-neutral, broader in a single draw, indifferent to what you wear — and unable to tell you anything about your recovery, because it never sees it.
Choose WHOOP Advanced Labs if
- You already wear a WHOOP and pay the membership. The integration is the product, and you have paid for half of it.
- You want frequent repeat testing. At four or six tests a year nothing here competes on cost per draw.
- You want the cheapest serious entry point: the $69 Basic Health Panel at 53 markers.
- You want Galleri at $799 rather than $949 direct, having read the section above.
- You are not in Arizona, Hawaii, Wyoming, North Dakota or South Dakota.
Choose Function Health if
- You want the most distinct markers in a single draw. 100+ at the annual visit beats 75.
- You do not want a wearable, or you wear something other than a WHOOP and intend to keep it.
- You want imaging in the same catalogue. Function sells MRI, CT and brain testing as add-ons; WHOOP does not.
- You want one annual price with no hardware dependency and no device that stops working when you stop paying.
Where Merios fits
Merios is analysis software for blood tests you already have. It parses lab PDFs from any lab — including a WHOOP Advanced Labs report or a Function Health export — tracks markers over time, and combines them with Apple Health data. It costs less than either product here because it includes no blood draw, which is most of what you are paying WHOOP and Function for. It is a different category, not a cheaper version of these two; we cover that category in our roundup of blood test tracking apps.
When Merios is the wrong choice
We would rather you buy the right thing than the thing we sell. These are real cases where WHOOP Advanced Labs or Function Health is the correct purchase and Merios is not:
- You do not currently get bloodwork and do not want to arrange it. Merios has no lab and cannot order a draw. Buy WHOOP's $69 Basic Panel or a Function membership.
- You want a clinician to look at your results. Merios has none, is not a medical service, and cannot escalate a dangerous value to a human. Both alternatives include clinician review.
- You wear a WHOOP and want the tightest integration. WHOOP's own labs land inside the app you already use, with no upload step. Merios can ingest WHOOP data, but the first-party path is smoother.
- You want cancer screening or imaging. Merios does not do Galleri, MRI or CT. Both alternatives do.
- You want maximum breadth in one draw. Merios adds nothing to a panel you never ordered. Function's 100+ test annual visit is the widest single draw here.
- You are not in the Apple ecosystem. Much of the Merios value is Apple Health integration. Without an iPhone, much of the product does not apply.
The bottom line
On verified 4 September 2026 prices, WHOOP Advanced Labs at $349 for two comprehensive draws and Function Health at $365 for two broader draws are close enough that price does not decide this. Price per biomarker — $2.33 against $2.28 — decides it even less.
What decides it is whether you wear a WHOOP. If you do, the integration is worth real money and nothing else here offers it. If you do not, dropping the membership gate has made Advanced Labs available to you and simultaneously less interesting: what remains is a competent 75-marker Quest panel with a clinician report, against a product measuring a third more in one sitting for six dollars more.
Buy on what you can verify: distinct markers per draw, whether you will still wear the same device in three years, and whether you can get your values back out of the app you put them into.
