Why At-Home Blood Tests?

At-home blood testing has exploded from a niche biohacker tool into a mainstream longevity category. Services like Function Health, InsideTracker, and Superpower promise 100+ biomarkers from a single draw — but “100 biomarkers” means wildly different things depending on the provider. Some count calculated ratios as separate markers; others bundle add-on panels that cost extra. The category’s biggest controversy — Function Health’s 2026 lawsuit against Superpower over deceptive biomarker-count marketing — proves the comparison gap is real.

What We Compare

Every service in our comparison is evaluated on:

  • Normalized biomarker coverage — we count unique measured analytes, not calculated ratios or marketing bundles. A 100-biomarker claim that includes 30 calculated ratios is reported as 70 measured markers.
  • Cost-per-biomarker — total annual membership ÷ unique measured analytes. The single most useful number for value comparison.
  • CLIA/CAP lab partner status — which reference lab processes the samples, and whether they hold both CLIA certification and CAP accreditation (the gold standard for US clinical labs).
  • Biological age / longevity scoring — which services offer epigenetic or multi-marker biological age estimates, and what the methodology is.
  • Actionable reporting — do results come with clinician interpretation, AI-generated recommendations, or raw data only?

Key Findings (2026)

  1. Function Health ($499/yr) offers the densest panel at 110+ measured biomarkers per draw, with Quest Diagnostics as the CLIA/CAP lab partner. Cost-per-biomarker is among the lowest in the category at ~$2.30/marker/draw.

  2. Superpower’s “100+ tests” marketing is under legal challenge. Function Health alleges deceptive counting. We independently verified that Superpower’s standard panel measures ~65 unique analytes with several calculated ratios counted as separate tests.

  3. InsideTracker remains the best for actionable recommendations — its InnerAge 2.0 biological age model and food/supplement/exercise prescription engine are unmatched. But at $589/yr for the Ultimate plan with fewer markers than Function, value-per-biomarker is lower.

  4. Finger-prick services (Everlywell, LetsGetChecked) serve a different audience — fewer markers, faster results, lower commitment. Not comparable to full-panel longevity services but valid for targeted screening.

  5. No service is a substitute for physician-ordered bloodwork. All at-home services use the same CLIA-certified labs as your doctor, but interpretation depth varies. SiPhox and Lifeforce include clinician consults; Function and Superpower do not.

Fig. IV · Questions

Frequently asked.

Are at-home blood tests accurate?

Yes — for properly collected samples processed by CLIA-certified labs. Function Health, Lifeforce, InsideTracker, Everlywell, and LetsGetChecked all use Quest Diagnostics or Labcorp partner labs, which are the same labs your doctor uses. Accuracy issues arise from collection problems (insufficient sample, capillary vs venous draw differences) more than the lab itself.

Do at-home blood tests require a doctor?

Most US providers route orders through a contracted physician network (PWN, OrderForMe) so no personal doctor visit is required. Some states (NY in particular) restrict direct-to-consumer lab ordering and require a clinician review step. Function Health and Lifeforce include physician oversight; Everlywell ships kits that you mail back without a clinical visit.

Are at-home blood tests covered by insurance?

Direct-to-consumer panels are typically not covered, but they are FSA and HSA eligible — you can pay with your tax-advantaged account. If you want insurance reimbursement, you generally need a doctor's order routed through a network lab, which is the traditional path most DTC providers explicitly bypass.

How accurate is Everlywell?

Everlywell uses CLIA-certified partner labs, so the lab analysis itself meets the same standards as a clinic draw. Limitations are practical: many panels use fingerstick rather than venous draws, which limits the biomarker set and can introduce sampling variability. For broader panels including ApoB, Lp(a), and full lipids, traditional venous draw services like Function Health are more comprehensive.

CLIA-certified vs CLIA-waived — what's the difference?

CLIA-certified labs can run any complexity of test, including the lipid panels, hormone assays, and HbA1c that biohackers care about. CLIA-waived labs handle low-complexity tests only (fingerstick A1c, urine dipsticks). Every reputable at-home blood test brand uses a CLIA-certified partner lab — confirm the lab name (Quest, Labcorp, Boston Heart) before ordering.
