If you are searching for Function Health alternatives, the useful question is not which product is best. It is what you are trying to replace: a cheap blood panel, the same Quest draw without the membership wrapper, labs bolted onto a wearable, an at-home collection, a physician directing care, or software for results you already own. Those are six different purchases, not a ranking.
Every price below was checked against the vendor's own page on 4 September 2026, and each row links to the page we checked. Where a vendor does not publish a price, we say so rather than estimating one.
Who publishes this page, and why that matters
This page is published by Merios, which makes blood-test tracking software. Merios competes with several products listed here. You should read it knowing that.
Because of that conflict, three rules govern this page. Merios is not the subject of it and is never ranked first on it. Merios appears in exactly one row of the table below — the row for people who already have results and want to track them — plus one short section describing the cases where you should not use it. And there are no affiliate links anywhere on this page: no referral codes, no tracked links, no commission on anything you buy from anyone named here. We make nothing whichever way you go, which is the only reason a page like this can be written honestly by a competitor.
If you want a comparison where Merios is a candidate, read our own head-to-head against Function Health and discount it accordingly. For a straight two-way on the category leaders, see Function Health vs Superpower. For Function's own cost stack in detail, see what Function Health actually costs.
How we picked
Criteria, stated before any verdict, in weighted order:
- Price verified against the vendor's own page, on a stated date, not against secondary reviews or aggregator sites.
- Cost per biomarker, computed by us from the verified price and the marketed count. No vendor in this category publishes it.
- What the price actually buys — one panel, one year, one draw or two, and whether the count is an annual total across multiple draws.
- Who reviews the results, if anyone: a physician, a nurse practitioner, a dietitian, a coach, or an algorithm.
- Collection logistics — patient service center, mobile phlebotomy, or at-home kit.
- Whether the vendor publishes prices at all. A company that hides pricing behind a signup form is a worse purchase than one that does not, and we say so where it applies.
We did not accept any vendor's comparison of a rival. Most publish one; all are marketing.
Verified prices and cost per biomarker
Function Health is the benchmark row, not the winner. Cost per marker is our arithmetic on the vendor's own numbers, and every count carries the caveat in the section below it.

Three warnings about that last column before you use it.
A marker is not a standard unit. Function counts "lab tests," Superpower counts "biomarkers," Ulta counts biomarkers across component tests. One test can report several values, and several vendors count calculated ratios alongside things actually measured. Comparing 160 of one to 150 of another is not like for like, and nobody publishes a reconciliation.
Annual counts hide the second draw. Function's 160+ is 100+ at the annual visit and 60+ three to six months later, per its own FAQ, and the mid-year test does not roll over if you skip it. Superpower's 150+ is a baseline plus a retest. If you only ever do the first draw, your real cost per marker is roughly 60 percent higher than the table says for both.
One-time panels and memberships are not the same product. Ulta's $204.95 buys one draw; Function's $365 buys a year. Read the table by segment, not down the column.
Segment by segment
Lowest verified cost per marker
Hundred Health, $199 per year, includes 100+ lab tests, testing through 5,000+ labs or at home, a clinician-reviewed 100-day protocol, and HSA/FSA eligibility. A $499 premium tier also exists. At $1.99 per test it is the cheapest lab-inclusive membership we could verify, undercutting Function by roughly 13 percent per marker. The trade-off is depth: 100+ against Function's 160+, and no imaging catalogue.
Cheapest single panel
Ulta Lab Tests resells Quest panels without a membership. Its Comprehensive Wellness Panel is $204.95 for 72 biomarkers; the Ulta Wellness Advanced Health Screening Panel is $233.95 for 68; the confusingly similar ULTA Comprehensive Wellness Panel is $652.95 for 126, listed against a $2,086.16 reference price. Ulta rotates weekly promotions, so your price may differ from ours. Nobody reviews your results. If that is your plan, start with how to read blood test results and what belongs in a longevity panel.
The same labs without the membership markup
Function draws through Quest, so you can buy from Quest yourself: the Elite Health Profile is $399 plus a $6 physician service fee, covers 85+ markers, and includes the option to discuss results with an independent provider at no extra charge. Labcorp OnDemand's Advanced Health Panel is $399 for 65+ markers.
Note what that means: going direct to the lab is more expensive per marker than Function, not less. Function buys volume at a negotiated rate and passes some of it on. What the higher unit price buys is no annual commitment, no auto-renewal, and no membership to cancel. See getting a blood test without a doctor for how ordering works.
Wearable-integrated
WHOOP Advanced Labs now sells panels without a WHOOP strap or subscription — its own page states "no subscription or wearable required." The Comprehensive Health Panel is $199 for 75 biomarkers; a Basic Health Panel is $69 for 53; the specialized Heart, Metabolic, Performance, Men's and Women's panels are $299 each for 77 to 90; Galleri multi-cancer screening is $799. A clinician reviews results and provides an action plan. If you already wear a WHOOP, the appeal is recovery and sleep data sitting next to the labs — the logic we cover in blood test tracking apps.
At-home collection
SiPhox Health is the option if you will not go to a patient service center. Its pricing page lists $295 for a one-time kit, $165 per kit billed quarterly, or a membership at $145 for the first six months and then $85 per kit; collection uses an upper-arm EasyDraw device rather than a clinic visit. The core kit covers 17 biomarkers, with broader panels advertised up to 62 markers. Per marker this is the most expensive route on the page by a wide margin. You are paying for never leaving the house, which for some people is the difference between testing and not testing.
Function also offers mobile phlebotomy, so at-home is not unique to SiPhox. Not needing a phlebotomist is.
Physician-led
Lifeforce is a different product wearing similar clothes. Its landing page lists a first diagnostic at $199, reduced from $349, then $149 per month, covering 50+ biomarkers tested four times a year with four 45-minute clinician consultations. Annualized, year one is roughly $1,987. A Core Annual plan is $599, reduced from $699, with two tests and one consultation. Do not compare that to Function on price per marker: you are buying a clinician relationship, and 50 markers is under a third of Function's count.
Marek Health occupies the same space — coaching plus clinician-prescribed care, popular with people optimizing hormones. It publishes no prices anywhere on its public site; you have to sign up to find out. Treat unpublished pricing as a real cost of the product.
Membership plus at-cost labs
Mito Health charges $9 per month for membership and states its panel price is "our cost to provide the test, plus the lab's ordering fees," advertising panels "from $80." Its shop lists Essential at 117 biomarkers, Core at 138, Ultra at 178. Actual panel prices appear only at checkout, so we cannot compute a cost per marker, and neither can you before starting an order. A per-visit draw fee also applies and varies by provider.
You already have results and want to track them over time
This is the row Merios occupies, and it is a different category rather than a cheaper version of the others. Merios parses lab PDFs from any lab, tracks markers across years, and combines them with Apple Health data. Free Basic, $14.99 per month for Pro. It includes no blood draw at any price, which is most of what you pay Function for. If your employer, insurer, or physician already runs a comprehensive panel, the draw is a sunk cost and tracking is the gap. If not, this row solves nothing on its own.
Outside the United States
Function Health is US-only. Its FAQ states it operates in 2,000+ Quest labs across 48 states, and specifically not Rhode Island, Hawaii, or Puerto Rico.
In the UK, Medichecks sells an Optimal Health blood test covering 59 biomarkers at £249.00 list, £199.20 when we checked, with a doctor's comments included by default and the option to opt out of them. Clinic venous collection is free; a home nurse visit adds £59.
In Canada, Biomi lists memberships at CAD $279 for a 40-biomarker analysis, CAD $549 for 60 with once-yearly testing, and CAD $1,199 for 65+ with twice-yearly testing, drawn through 200+ partner labs.
For continental Europe we could not verify a pan-European equivalent; availability and pricing are country-by-country, and we will not quote a figure we have not checked. The markers worth paying for are the same everywhere: see biomarkers worth tracking for longevity.
When Merios is the wrong choice
We would rather you buy the right thing than the thing we sell. Real cases where something else on this page is the correct purchase:
- You do not currently get bloodwork and do not want to arrange it. Merios has no lab and cannot order one. Buy Function, Hundred Health, or a Quest panel.
- You want a clinician to look at your results. Merios has none and is not a medical service. Function, Lifeforce, WHOOP Advanced Labs and Quest all include some form of review.
- You want imaging or cancer screening. Merios does no MRI, CT, or Galleri. Function and WHOOP do.
- You want one price that covers everything. Merios' sticker price excludes the lab fee entirely. Add a comprehensive panel and your annual total can exceed $365, at which point Function is cheaper and more complete.
- You need an at-home draw. Merios cannot arrange any collection. SiPhox, Function, and Hundred Health can.
- You are not in the Apple ecosystem. A large share of Merios' value is Apple Health integration; without an iPhone, much of the product does not apply.
What we could not verify
Stated plainly, because the omissions matter as much as the numbers:
- Marek Health publishes no prices. Not for panels, coaching, or consultations.
- Mito Health does not list panel prices on its shop page; only the $9 monthly membership and a "from $80" figure are public.
- Function's add-on test prices are not published, beyond imaging. Third-party sites circulate ranges; none cite Function, and we will not repeat them as fact.
- Function's New York and New Jersey price is not published. Its FAQ says testing there "can cost more due to state regulations" without a figure.
- A widely repeated figure of roughly $389 for 119 Ulta markers matches nothing we found on Ulta's live pages on 4 September 2026. The panels we did verify are listed above.
- SiPhox's per-panel biomarker counts beyond the 17-marker core kit are not itemized on its pricing page.
If you are still deciding how often any of this is worth repeating, how often you should actually get bloodwork is a bigger lever on your annual cost than the difference between any two products here.
