# Function Health Review (2026): What $365 Buys, Wait Times, and the À La Carte Alternative

*A plain-numbers look at the Function Health membership — the panel, the two draws, how long results and the clinician plan take, where it is sold, and what the same lab tests cost if you order them once instead.*

> **Disclosure:** TestWell sells the à la carte alternative to the memberships reviewed here. Every figure on this page is read from Function Health's public pages (or a linked third party) on 2026-10-22 and linked in Sources; where the memberships are the better buy, the page says so. We have not been paid by, and are not affiliated with, Function Health.

> Function Health is a $365-a-year membership: an annual blood draw of about 115 markers at Quest, a mid-year draw that repeats about 60 of them, first results in roughly 48 hours, and clinician-reviewed insights that reviewers report take three to four weeks. If you want 100+ markers tracked every year with a written plan, it is a fair price per marker — about $3.17. If you want specific answers (lipids and ApoB, thyroid, A1c, vitamin D, hormones), the same Quest tests cost $14.99–$45 each, once, with results in 1–3 days and no renewal.

## Recommended tests

All prices are cash-pay plus one $6 lab processing fee per order; physician authorization is included.

## What does the Function Health membership include?

Function Health sells one product: an annual membership at **$365**, charged yearly. The brand's headline is "160+ lab tests annually, tested 2x/year". Read against its [What we test](https://www.functionhealth.com/what-we-test) page, that works out as:

- **Two draws a year at Quest Diagnostics.** An annual draw of roughly 115 markers, then a mid-year draw that repeats about 60 of them.
- **116–118 per annual draw**, of which 102–103 measured directly and 14–15 calculated (ratios, eGFR and similar derived values).
- **A clinician-reviewed write-up** of every result with a personalized protocol, plus in-app chat.
- **An add-on catalog** — MRI/CT scans through Ezra, Galleri, Alzheimer's markers, allergies, PFAS, heavy metals — billed separately.

The base panel is genuinely broad: advanced lipids with particle number and size, omega-3 fatty acids, lead and mercury, a full thyroid set, autoimmunity screens and a urinalysis sit alongside the CMP/CBC/lipid basics. That breadth is the product. Nothing on it is exotic to the lab — every item is an ordinary Quest test with a CPT code — but assembling it yourself one test at a time costs more than $365.

## How long do Function Health results take?

Two clocks run. The first is the lab's: Function says *First results typically start arriving within 48 hours of the draw*, and because Quest performs the tests, most of the routine chemistry posts inside a few days while specialty markers (heavy metals, omega-3 index) trail by a week or two — the same lab turnaround anyone gets at Quest.

The second clock is the clinician review. Function does not publish a turnaround for the written insights; independent reviewers in 2025–2026 report **three to four weeks** from draw to a complete plan. If you are deciding between Function and Superpower on speed-to-plan, that is the real difference: Superpower's protocol is generated the moment results land (results in about ten days), while Function's is slower but human-reviewed.

Scheduling is a third, smaller clock. Draws happen at 2,000+ Quest Diagnostics locations; appointments are self-booked and availability is the usual Quest availability for your zip code.

## Who is Function Health for?

Function suits three kinds of people well:

- **The annual-baseline tracker.** You want 100+ markers measured every year, with the same list repeated so trends are comparable, and you will read the write-up. Per marker, nothing à la carte matches $365 for that list.
- **The person who wants someone else to interpret.** A clinician-reviewed summary of every out-of-range result, in plain language, is the part of the product you cannot buy from a lab or from us.
- **The add-on buyer.** If you are already planning a scan or Galleri, having them inside one account with one record has real convenience value.

It suits these people less well:

- **You want a few specific answers.** A lipid panel, ApoB, TSH, A1c and vitamin D together cost about $146.95 once at TestWell — a third of the membership — and arrive in days.
- **You live in Hawaii, Rhode Island or Puerto Rico** (Function is not available there), or in **New York or New Jersey**, where state fees are charged at the facility on the day of the draw and the amount is not published.
- **You want Labcorp.** Function draws at Quest only.
- **You want to retest one thing in three months.** The membership's second draw is a fixed subset six months out; outside it you are buying à la carte anyway.

## What do the same markers cost once, without a membership?

Here is the arithmetic the membership pages do not show. Every Function marker is a Quest test you can order individually. At TestWell's prices (plus one $6 lab processing fee per order):

| What you want | Once, à la carte | Function Health |
| --- | --- | --- |
| The four tests a physical orders (CMP, CBC, lipids, TSH) | $49.99 — General Wellness Panel | $365/year for the full list, twice |
| Heart check: lipid panel + ApoB + hs-CRP | $90.97 |
| Metabolic + nutrients: A1c, fasting insulin, vitamin D, B12, ferritin | About $150 |
| The whole 49-test Total Body Panel | $599.99 — more per marker than the membership |

The last row is the honest one: if you truly want a 100-marker list every year, Function (or Superpower at $199) costs less per marker than any à la carte panel, ours included. À la carte wins on *targeting* — you pay for the ten things you care about and skip the ninety you do not — and on speed, lab choice and the absence of a renewal.

To price your own list against the membership, use the [panel builder](https://www.test-well.com/tools/build-your-panel): pick markers, see the running total next to $365 and $199, and order the set in one checkout if it is cheaper. The full arithmetic — Function's published list mapped to our catalog, what the most-ordered tests cost once, and the breakeven — is in [The membership math (2026)](https://www.test-well.com/research/membership-math-2026).

## Where Function Health is the better buy

We sell the alternative, so this list is stated without hedging:

- Clinician review of every result with written insights and a personalized protocol.
- Two draws a year inside the price — the mid-year retest tracks ~60 markers.
- Built-in AI chat plus ChatGPT, Claude and Perplexity integrations for your results.
- Deep add-on catalog: MRI and CT scans (Ezra), Galleri, Alzheimer's, allergies, PFAS, heavy metals.
- Advanced lipids (NMR particle number/size), omega-3 fatty acids, lead and mercury in the base panel.

And against Superpower specifically: Function tests more per draw (102–103 measured directly versus 57 measured directly), tests twice a year, and reviews results with a clinician rather than an AI protocol. It costs $166 more and the plan arrives weeks later. The two are compared line by line in [Function Health vs Superpower](https://www.test-well.com/compare/function-health-vs-superpower).

## Is Function Health legit?

Yes, in the sense people mean when they search it: the tests are performed by Quest Diagnostics at CLIA-certified laboratories, orders are authorized by licensed clinicians, the company is a real venture-backed business operating in 48 states, and the membership is HSA/FSA-eligible. The questions worth asking are not about legitimacy but about fit — whether you will use 100+ markers, whether a three-to-four-week plan matters to you, and whether you would rather pay $365 once a year or $30–150 for the specific tests you want.

Two practical cautions apply to every direct-to-consumer panel, Function's and ours included: a wide screen in a healthy person turns up some out-of-range values by chance, and a lab result is not a diagnosis. Take anything flagged to your own clinician.

## Frequently asked questions

### How much does Function Health cost?

$365 a year, charged annually, covering two blood draws at Quest. New York and New Jersey state fees are charged at the facility on the day of the draw (amount not published). Add-ons such as scans and Galleri are billed separately.

### How many biomarkers does Function Health test?

116–118 per annual draw (102–103 measured directly, 14–15 calculated), with a mid-year draw repeating about 60 — the brand's headline is "160+ lab tests annually, tested 2x/year".

### How long does Function Health take to get results?

First results typically start arriving within 48 hours of the draw. The clinician-reviewed plan has no published turnaround; independent reviewers report three to four weeks.

### Does Function Health take HSA or FSA?

Yes. The membership is HSA/FSA-eligible. TestWell orders are too — every order comes with an itemized receipt listing CPT codes.

### Is there a Function Health promo code?

Function runs occasional referral and seasonal offers; there is no standing discount code we can verify, and we do not publish third-party codes. The pay-per-test alternative is $14.99–$45 a test with no code needed.

### Can I get the Function Health tests without a membership?

Yes — every marker is an ordinary Quest test. TestWell sells them individually (from $14.99) and in panels (General Wellness Panel $49.99; Total Body Panel $599.99). If you want the whole 100+ list every year, the membership is cheaper per marker; if you want a specific set, à la carte is cheaper and faster.

### Function Health or Superpower?

Function: more markers per draw, two draws, clinician review, $365, slower plan. Superpower: $199 ($399 in NY/NJ), one draw, 57 measured markers, instant AI protocol, results in about ten days. See the side-by-side at /compare/function-health-vs-superpower.
