The best biomarker testing companies in 2026

Consumer biomarker testing now runs from one-off lab orders to annual memberships with 100+ markers and clinicians who can prescribe. The difference that matters most is not the biomarker count but what you pay in a year and whether anyone acts on the results.

#3 OneTwenty logo
Best for quarterly bloodwork

OneTwenty

Best for: People who want their blood retested every 90 days (a 101-marker baseline plus three follow-up panels a year) and want custom supplements and prescriptions, at published prices, driven by those results in one membership.

Built around retesting: a 101-marker baseline, then a 20 to 40 marker follow-up panel every 90 days, all inside the $499 membership, so you see whether changes are working instead of testing once a year. Custom supplement packs (from $45/mo) and prescriptions are priced on its site and run from the same results. It ties Quest on score (9.9) and sits just behind InsideTracker, which serves every state; OneTwenty serves 49.

Pricing page (seen 2026-11-05; the page says its prices were checked on 2 November 2026): $499 a year, billed annually, for four lab panels: a 101-marker baseline (OneTwenty's own count) plus three follow-up panels of 20 to 40 markers, one every 90 days ('161 to 221 lab results a year'). Walk-in draws at Quest are included; an at-home draw is $99 per draw. NY and NJ: $749 a year because Quest cannot be used there. Add-ons: custom supplement packs from $45/mo; extra lab panels 'at cost' (no prices listed). Medications are priced per product on each treatment page: metformin and sildenafil $49/mo, tadalafil $79/mo, GHK-Cu cream and testosterone cypionate $99/mo, enclomiphene, glutathione (injection or nasal) and oxytocin $129/mo, sermorelin and NAD+ (injection or nasal) $149/mo, compounded semaglutide $179/mo, PT-141 $199/mo, tirzepatide $279/mo or $749 billed quarterly.

Watch out for

  • The annual membership is non-refundable after a 7-day window, and only if no service has started (3% fee applies)
  • Not a medical practice: prescriptions come from unnamed third-party telehealth providers, and the site does not say whether they are physicians or NPs or whether visits are by video

What we like

  • Low membership fee ($9/month or $99/year) with member and non-member panel prices listed for each lab and state
  • Panels can be bought without a membership, and no doctor's order is needed (orders are signed by a Mito-network physician)
  • 7-day full refund window on membership charges and lab orders before labs are run
  • Lists Quest, Labcorp and BioReference options, plus at-home kits in all 50 states and DC

Watch out for

  • Lab tests are not included in the membership; each panel is a separate purchase plus a per-visit draw fee shown only at checkout
  • Membership cancellation is by email to help@mitohealth.com; no self-serve flow is documented
  • No lab visits in Rhode Island or Hawaii; NY/NJ panels cost roughly twice the Quest price
  • Clinician review of results is only for members; Mito says it is not a medical provider and consults are 'health education, not medical advice'
Cancelling

FAQ: 'you can cancel or re-join Mito membership anytime. For cancellations, please reach out to help@mitohealth.com.' Membership page: '$9/mo, cancel anytime'. Terms of Service (last updated 2026-10-01) s.8.4: memberships auto-renew at the then-current rate until cancelled. s.8.5(a): each membership charge, including renewals, and each lab order can be fully refunded within 7 days if labs have not been run; from day 8 refunds are case by case with an 8% fee deducted; no refund once labs have been run or a kit sample is received.

Where it is available

FAQ: at-home kits, scans and fitness tests can be ordered in all 50 states and DC; lab testing is available in the same places except Rhode Island and Hawaii, where lab visits are not offered, so residents there must have the draw in another state. Not available in Puerto Rico or other territories. Panel pages: Quest pricing in all states and DC except HI, NJ, NY and RI; NY and NJ use BioReference at higher prices ('prices include a fee to cover the state's compliance and handling requirements'). Mito Ultra (includes Galleri) is not available in AZ, HI, NJ, NY or RI.

Pricing

Everlywell 360 page (seen 2026-11-05): '$399 / billed annually' for one 83-biomarker lab test per year at a Quest site (blood and urine), a results dashboard with biological age and 'WellScore', and a Care Plan from Everlywell's clinicians. 'Everlywell 360 + Consult' adds a 1:1 visit with a licensed provider who can prescribe; its price is not shown on the page (the FAQ implies $100 of the price is the consult, via a $100 partial refund). Follow-up labs and prescriptions are not included. Separately, at-home kits sell one-off (e.g. Men's or Women's Health Test $249, Thyroid $149, Cholesterol & Lipids $49), and Weight Care+ costs $99/month on a 12-month commitment or $139/month on a 3-month commitment, with GLP-1 drug costs extra ($900 to $1,400/month without coverage, per Everlywell). FSA/HSA eligible.

Prices as listed on November 5, 2026. They change often; confirm at checkout.

  • In-house clinicians (MDs, DOs and NPs) can prescribe through the optional consult
  • Membership price and most test and program prices are published
  • FSA/HSA eligible

Watch out for

  • Price of the 360 + Consult tier is not shown on the 360 page
  • Agreed to a $5 million settlement of a 2024 class action over sharing purchase data with Facebook and Google; a separate suit challenges its food sensitivity test claims

Cancelling

Everlywell 360 FAQ: 'You can cancel your membership at any time by contacting our Everlywell 360 Concierge team at everlywell360@everlywell.com.' The membership is charged annually on the signup date.

Consults cancelled within 24 hours may incur a $25 fee. Other programs differ: Weight Care+ requires a 3- or 12-month commitment, and legacy kit subscriptions require 48 hours' notice and a minimum number of kits (3 monthly, 2 quarterly or bi-annual) before cancelling.

Where it is available

Tools for this decision

How we ranked these

Same rubric, plus whether the service offers treatment or testing only, because those are different products. Facts come from each provider’s own pricing, FAQ and terms pages, with regulator and court records where they exist. Scores are produced by a fixed table, so the same facts always give the same score. See the rubric.

Best biomarker testing companies: FAQ

What is the best biomarker testing companies provider?

InsideTracker ranks first, scoring 10.0/10 on our five-criterion rubric. People focused on nutrition and fitness optimization who want a periodic blood panel with algorithmic recommendations and no prescribing.

How were these providers ranked?

Every provider is scored on the same five weighted criteria: licensed states (24%), labs included (24%), cost transparency (18%), cancellation friction (17%) and formulary breadth (17%). Who prescribes is shown on each review but not scored. Facts come from each provider’s published pages, checked November 5, 2026. Scores marked * are provisional because one or two criteria could not be verified.

Which of these include lab work in the price?

InsideTracker, Quest Health, OneTwenty, Function Health, Superpower, Rythm Health, Lifeforce, SiPhox Health, Everlywell include the initial lab work in their published pricing. The others bill labs separately or did not publish it.

Do any of these providers have regulatory or legal issues?

Quest Health, Superpower, Everlywell have a public regulatory or legal record, such as an FDA warning letter or lawsuit. Details and sources are on each review page.

Do providers pay to be on this list?

No. Placement is set by the rubric score. Where a provider pays us a referral fee, its link is labelled “Paid link”, and that does not change its score.
