Function Health review: cost, tests and complaints

What Function Health costs

The membership is billed once a year. The pricing page frames it as "$1 per day" and says the $365 offer applies to the first year, is not available in New York or New Jersey, and renews at the then-current price ^[1]. Function says the membership is HSA and FSA eligible ^[2].

Costs that sit outside the $365

• Renewal at the price in effect at the time, not a locked $365 ^[1].
• On-demand tests between the two scheduled draws, at an extra member cost ^[2].
• Imaging and cancer screening add-ons, priced separately ^{[2] [3]}.
• Any follow-up care for an abnormal result: our research found no follow-up visits bundled into the membership.

What the membership includes

Members get two rounds of blood work a year, every six months, covering what Function describes as 160+ lab tests, plus clinician review of the results ^[2]. Function bought the imaging company Ezra in May 2025 and launched a $499 full-body MRI at that time ^[5]. Ezra's site now lists its Annual MRI at $999, or $899 with a Function membership, so the $499 figure in older coverage is not the current list price ^[3].

We saw no waitlist or invite requirement on the site on Oct 17, 2026; signup was open ^[2]. For a side-by-side with the cheaper one-panel option, read Superpower vs Function Health. For a membership that adds nutrition coaching, see Function Health vs InsideTracker. For blood work every three months with coaching, see our Lifeforce review ^[14]; for a one-hour in-person check with no MRI, see our Neko Health review ^[15]. Our longevity blood test comparison covers the wider market.

Evidence limits on the extras

Full-body MRI

The American College of Radiology says it "does not believe there is sufficient evidence to justify recommending total body screening" for people without symptoms, risk factors or a family history that suggests disease ^[6]. At Weill Cornell, about 90% of the first 160 or so screened patients had some finding, about 30% needed follow-up, and about 1% had a malignant or suspected malignant finding ^[7]. Prices and scan differences are on our full-body MRI cost page and in Ezra vs Prenuvo.

Galleri

Galleri is not FDA-approved. An FDA advisory panel voted in its favor on Sept 23, 2026 (effectiveness 6 to 4, benefit-risk 7 to 2), and the agency's decision was still pending ^[8]. In GRAIL's PATHFINDER 2 study of 23,161 adults aged 50 and older, 0.93% got a cancer signal and the positive predictive value was 61.6%, meaning roughly 4 in 10 positive signals were not cancer; the test found 40.4% of cancers diagnosed in the study period ^[9]. The NHS-Galleri randomized trial missed its primary endpoint ^[10]. More on our Galleri test page.

FDA and complaint record

Function Health sells lab testing, not prescription drugs, so the FDA letters we track against telehealth drug sellers are a weaker signal here. Even so, we checked: no letter to Function Health appears in our FDA warning letter tracker, which holds 68 letters dated December 2024 to September 2026.

Who it fits, and who should look elsewhere

• Fits: people who want a wide panel repeated twice a year and can use HSA or FSA money ^[2].
• Look elsewhere if one panel a year is enough: Superpower lists $199 a year for 100+ biomarkers ^[11]. See our Superpower review.
• Look elsewhere if your question is heart risk: a coronary calcium scan typically costs $100 to $150 cash ^[12]. See coronary calcium score.
• Look elsewhere if you live in New York or New Jersey and want the $365 rate, which excludes those states ^[1].
