The Panel Audit

A biomarker count is a marketing number until somebody checks it.

Consumer testing services compete on how many biomarkers they advertise. That number routinely includes values calculated from other results rather than separately assayed. This audit keeps the advertised count and the confirmed count in separate columns.

Prices are headline consumer prices and exclude add-ons. Verify current pricing with the provider before purchase, since this category re-prices frequently.

Service by service

Function Health

Annual membership · $365 per year

Audit pending

Positioning

The category leader by scale and funding. Two draws per year, a broad panel, and a consumer dashboard.

What to watch for

The two draws are scheduled apart rather than combined, which some members find inconvenient. The written interpretation is not a substitute for a consultation.

Marker count

Marketing describes 100+ biomarkers across roughly 160 tests. We have not yet independently confirmed how many are directly assayed versus calculated. Audit in progress.

Clinical access

Results include written clinician review notes rather than a scheduled consultation. Users commonly report the written interpretation reads as generic.

Superpower

Annual membership · $199 per year

Disputed

Positioning

The aggressive price disruptor in the category, with heavy consumer marketing.

What to watch for

Read the litigation before relying on the advertised marker count or the clinical-access claim. Both are contested.

Marker count

The advertised marker count is the subject of an active Lanham Act false-advertising suit filed by a competitor in January 2026, which alleges the true count of direct lab measurements is substantially lower than advertised. The allegations are unproven and contested. We list this as disputed rather than taking a side, and our own audit is pending.

Clinical access

Marketing language around clinical access has been challenged in the same litigation. Confirm exactly who responds, with what credentials, and how quickly.

InsideTracker

Annual membership · $149 per year

Audit pending

Positioning

The long-standing incumbent, with the strongest following among endurance athletes.

What to watch for

Costs more per marker than newer entrants. Recommendations have historically been oriented toward supplement suggestions.

Marker count

Advertises up to 54 markers, a more modest claim than several competitors. Audit pending.

Clinical access

Algorithmic recommendations rather than a clinician consultation.

Marek Health

Clinic programme · $250 intake, plus panels

Audit pending

Positioning

Not a testing company but a cash-pay optimization clinic that prescribes. Its differentiator is that someone acts on the results with you.

What to watch for

The business model includes prescribing. That is the value for some people and the conflict for others: the entity interpreting your labs also sells the therapy.

Marker count

Panel composition varies by tier. Audit pending.

Clinical access

Includes video consultations with licensed providers. This is a genuine differentiator versus dashboard-only services.

Lifeforce

Clinic programme · $549 initial diagnostic

Audit pending

Positioning

Concierge-tier positioning with celebrity-founder marketing.

What to watch for

Among the highest costs per marker in the category, and revenue includes supplements and prescriptions sold alongside interpretation.

Marker count

Advertises 50+ markers. Audit pending.

Clinical access

Includes clinician and health coach access as part of membership.

Quest (consumer-initiated)

Lab marketplace

Verified

Positioning

The underlying laboratory that several consumer platforms run on. Buying direct removes the dashboard and the markup.

What to watch for

You get no interpretation and no longitudinal tracking. For people who know which tests they want, this is usually the cheapest path to the same assays.

Marker count

Sells individual clinical tests directly. Because you choose named tests rather than buying a bundled count, there is no marketing marker count to audit. Every result is a directly assayed clinical test.

Clinical access

No interpretation layer. You receive standard clinical results.

Labcorp OnDemand

Lab marketplace

Verified

Positioning

The other major reference laboratory selling directly to consumers.

What to watch for

As with Quest, the trade is price and assay quality against the absence of interpretation.

Marker count

Direct consumer access to standard clinical assays. No bundled marketing count to audit.

Clinical access

Results delivered without a consultation; an AI explanation layer has been added.

Everlywell

One-off test · $49 from, per kit

Audit pending

Positioning

Single-condition at-home kits. The earliest mainstream model in the category.

What to watch for

Built around one-off questions rather than longitudinal tracking. Self-collection introduces sample quality variability that venous draws do not have.

Marker count

Marker counts vary by individual kit rather than a single headline number.

Clinical access

Kit-dependent; most are self-collected at home without a consultation.
