InsideTracker Review (2026): Cost, 48 Markers and Renewal Terms

Below: the price in year one and after, what the panel measures and misses, who orders and reads the test, the cancellation window, and when InsideTracker still makes sense. The scorecard is on the InsideTracker review page, and every service is ranked on the best blood tests page.

What InsideTracker costs

Prices come from InsideTracker's own store (store.insidetracker.com, read October 31, 2026). The store refused automated readers on our citation check, so the figures below are as we read them by hand on that date.

Two things push the real cost up. First, the store says residents of New York, New Jersey, Rhode Island, Hawaii and Arizona must use a mobile phlebotomist, so every draw there costs more. Second, a sale price covers the first term only. Its terms of service say that a sale price is valid for the initial term only and that later memberships renew at the full retail price at the time of renewal. InsideTracker does not publish the renewal price on the store, so year two is an unknown until you see the renewal notice.

What the panel measures and misses

The store says "up to 54" biomarkers. The newest published list we could find names 49, and three of them apply to women only. After setting aside the one calculated value, we count 48 measured markers.

It covers ApoB, hs-CRP, fasting insulin, cortisol, total and free testosterone, ferritin, vitamin D and B12, plus a full blood count. It does not include Lp(a), homocysteine, PSA or thyroid antibodies, and estradiol is on the women's list only. If Lp(a) matters to you, you would buy it separately; our Lp(a) cost guide prices it at every lab store. Plan-by-plan coverage is on the biomarker table and the ApoB page.

Who orders the test, and who reads it

A physician in InsideTracker's network approves the order, and draws happen at Quest or through a mobile phlebotomy partner. Its terms of service state that all of its partner labs are CLIA-certified. You can check a lab on the CMS QCOR CLIA lookup.

No doctor reviews your results or meets with you as part of the plan. Recommendations come from InsideTracker's algorithm and science team. That is the main difference from Function, Superpower and Empirical, where clinicians review each result.

Cancellation and refunds

The cancellation window is unusually long. Its terms of service require you to cancel 30 days before the next recurring billing date to avoid the next charge, and say partly used billing periods are not refunded or credited. Miss that window and the renewal goes through.

Refunds are narrow. The same terms limit refund requests to 30 days from purchase or renewal, and rule out any refund on a blood test once the sample has been collected. Set a reminder 31 days before your renewal date if you plan to stop.

Privacy

InsideTracker's privacy policy says it has policies designed to comply with HIPAA standards for privacy and security. The same policy says anonymized blood test results, fitness tracker data and self-reported information may be included in disclosures to third parties for research. Our privacy comparison puts that next to every other service.

InsideTracker vs Function Health

Function measures about twice as many markers, includes Lp(a), adds a second draw and a clinician review, and costs less. Function's FAQ also says it "does not offer refunds for prior payments" (Function FAQ), so neither is generous on refunds. The full pairing is on Function vs InsideTracker, and cheaper options are in our Function Health alternatives guide.

Our verdict

InsideTracker is for people who want an app-led action plan and wearable syncing and do not need a clinician. On price per measured marker it ranks near the bottom of the memberships we track, and the 30-day cancellation window and unpublished renewal price add risk. In Hawaii, where Function, Superpower and Quest's own store do not sell, it is one of the few memberships available, with the draw at home. For most buyers, a cheaper membership on our price page measures more for less.
