The verdict
Function bundles 160+ lab tests a year across two Quest visits, with clinician review, for $365 the first year. The catch: renewal is at the then-current price, extras cost more, and in New York and New Jersey the lab may bill you separately. Trials of general health checks haven't shown lower mortality.
The trade-off
It's nonrefundable after 48 hours or once a specimen is collected, the renewal price isn't stated, and imaging, add-on tests and home draws cost extra.

About this price
This is the first-year price on Function's pricing page, shown as "$1 /day" and "Charged annually at $365", before tax. Membership renews at the then-current price, and the page doesn't give a renewal amount. Function says the $365 first year includes full access to 160+ lab tests in every state except New York and New Jersey. The terms say some or all lab fees in those states aren't included in the subscription fee and may be billed to you directly by the lab. A footnote also mentions a "Function Day offer" that expired 10/8/2026, without saying what it changed. Add-on tests, imaging and home draws aren't included. The FAQ lists the Annual MRI at $999 for members.
A GOOD FIT FOR
An adult in one of the 48 states Function serves who wants a broad blood panel twice a year, paid out of pocket, to track over time and discuss with their own clinician.
- You're an adult in one of the 48 states Function serves and want a broad lab panel twice a year
- You're fine paying out of pocket rather than through insurance
- You want your results tracked over time to bring to your own clinician
THINK TWICE IF
- Anyone in Rhode Island, Hawai'i or Puerto Rico, where Function says it isn't offered yet
- Anyone currently pregnant or under 18
- Anyone expecting a diagnosis, treatment or a replacement for their regular doctor
- Anyone who wants a refund after the first draw
- Anyone who wants a guaranteed renewal price
What still needs checking
- Renewal price after the first year
- How much the lab bills directly in New York and New Jersey
- Prices for add-on tests, the home draw and imaging other than the Annual MRI
- Turnaround for the complete panel
- Which accreditations, such as CLIA or CAP, the testing labs hold
- What the expired "Function Day offer" changed
The practical details.
| Exact variant | Annual membership, $365 first year, charged annually |
|---|---|
| Lab tests | 160+ a year: 100+ at the annual visit, then 60+ more in a follow-up 3 to 6 months later |
| Sample method | Blood draw at a Quest location (about 35 to 85 mL) |
| Home draw | A licensed specialist can draw blood at your home or office in select areas. Function lists it as an advanced add-on test, with no price shown |
| Imaging | MRI and CT aren't included, but members get member pricing. The FAQ lists the Annual MRI at $999 for members and shows no price for the other scans |
| Preparation | Fast for 8 hours before the test |
| Turnaround | First results typically start arriving within 48 hours of testing. The How it works page says results are ready around 2 weeks after an at-home draw appointment |
| Clinician review | Function says clinicians review every result and flag issues. Results include a clinician's summary and action items |
| Membership terms | Billed annually and auto-renews at the then-current price. You can cancel and rejoin anytime but can't pause. Cancellation generally takes effect at the end of the billing cycle |
| Eligibility | Adults 18+ who aren't currently pregnant, in 48 states (not yet Rhode Island, Hawai'i or Puerto Rico). In New York and New Jersey, some lab fees may be billed to you directly by the lab |
| Insurance and HSA/FSA | Function doesn't bill insurance. It lists the membership as HSA/FSA eligible, subject to your plan, with an itemized receipt in your account for reimbursement |
| Dimensions | No physical product. It's a lab-testing membership. |
| Materials | Not applicable. Function says it tracks your results in one secure place, with a web login and mobile apps. |
Before you buy
InstallationNo installation
No installation. Function says blood is drawn at one of 2,000+ Quest locations across 48 states. In select areas, a licensed specialist can come to your home or office instead. The How it works page lists this home draw among its advanced add-on tests, with no price shown.
WarrantyNo warranty
No warranty. Under the terms of service, Function's services come "as is", with no warranties of any kind. Function also doesn't warrant the accuracy, completeness or timeliness of lab results. The FAQ says the membership isn't a replacement for your health benefits or your doctor.
ReturnsUnder the terms of service, you can cancel for a full refund within 48 hours…
Under the terms of service, you can cancel for a full refund within 48 hours of your first purchase. That only applies before any specimen is collected or lab testing is done. After that, the membership and renewals are nonrefundable, and the FAQ says Function doesn't refund prior payments. Cancellation generally takes effect at the end of the billing cycle. You can't pause a membership, though the FAQ says you can cancel and rejoin at any time.

3-year planning total
$1,095.00Every field has a value. This is an estimate, not a quote.
Energy component: $0.00
Purchase + installation + years × (annual consumables + annual other) + watts/1000 × hours/day × 365 × years × $/kWh. Annualized allowances, not an exact replacement schedule. Excludes taxes, shipping, finance and resale unless entered.Replacement parts & cost assumptions
No scheduled consumable is listed. That does not mean zero maintenance or repair costs.
- There's no hardware, so the $365 yearly fee counts as a recurring membership cost and the upfront purchase is $0.
- The three-year figure assumes you renew at $365 a year. Function only states $365 for the first year and says membership renews at the then-current price. Years two and three may cost more.
- Add-on tests, MRI or CT imaging and home draws are optional extras, so they're left out. The FAQ lists the Annual MRI at $999 for members. The pages checked show no price for the other extras.
- In New York and New Jersey, the terms say some or all lab fees aren't included in the subscription fee. The lab may bill you for them directly, and Function doesn't say how much they are.
Evidence & sources.
Are longevity blood tests and biological-age clocks worth it? Our evidence review grades the research as Not supported. That grade is about the claim, not about this product.
- Manufacturer claimFunction describes itself as a healthcare technology company, not a laboratory or medical provider. It says independent third parties provide the lab and medical services, and that it doesn't offer medical advice, diagnosis or treatment.125 Test counts, clinician review and turnaround are Function's own statements. The pages checked name Quest as the lab partner and say the labs "meet the highest clinical standards". They don't state CLIA or CAP accreditation.
- Published studyA Cochrane review of randomized trials found that general health checks in adults had little or no effect on total mortality (RR 1.00, 95% CI 0.97 to 1.03; 11 trials, 233,298 participants; high certainty). They also had little or no effect on cancer mortality (RR 1.01, 0.92 to 1.12; 8 trials; high certainty). Their effect on cardiovascular mortality was probably little or none (RR 1.05, 0.94 to 1.16; 9 trials; moderate certainty).6 The authors concluded that general health checks are unlikely to be beneficial. These trials tested health checks in general, not Function's panel, so they don't measure this membership directly. No outcome trial of the membership itself was found.
