At-Home Biomarker Labs & CGM Programs

The at-home biomarker lab market exploded post-2022 alongside the consumer-CGM trend. Two flavors: (1) periodic blood panels with apps (Function Health, InsideTracker, Marek), and (2) CGM-with-coaching (Levels, Veri, NutriSense, Lingo). Useful for self-knowledge but annual basic labs through your PCP are mostly free under most US insurance and cover 80% of what these apps measure.

Periodic blood panels with apps

• ★ Function Health — paid (~$500/yr); 100+ biomarkers, twice yearly; clinician review; Mark Hyman-affiliated; 2024 mainstream wave (six-figure waitlist drained). The most comprehensive consumer panel.
  • https://www.functionhealth.com/
• ★ InsideTracker — paid ($200-700 per panel); fewer markers; longer track record; food + supplement recommendations from results.
• Marek Health — paid; HRT + comprehensive labs + provider; fitness-medicine flavored.
• Wild Health — paid; precision-medicine; provider-led.
• Quest MyChoice / LabCorp Pixel — paid; cash-pay direct lab orders without provider; cheaper a la carte.
• Empower / Lifeline Screening — paid; lipid + cardio markers.
• EverlyWell — paid; mail-in finger-prick; thyroid / hormones / food sensitivities; quality varies.
• LetsGetChecked — paid; mail-in similar to EverlyWell.

What basic insurance-covered annual labs cover (US)

For comparison, your annual physical via a PCP under most US insurance covers (often $0 copay):

• CBC (complete blood count).
• CMP (comprehensive metabolic panel — glucose, kidney, liver, electrolytes).
• Lipid panel (cholesterol).
• HbA1c (3-month glucose average).
• TSH (thyroid).
• Vitamin D (sometimes).
• Iron / ferritin (if requested).
• ★ This baseline covers most of what consumer panels charge $200-500 for. Ask your PCP.

CGM-with-coaching (overlap with Diabetes)

• ★ Levels — paid (~$200/yr program fee + sensor cost); meal-tagging + glucose response; targeted at metabolic-health-curious non-diabetics; partnered with Abbott Libre.
• Veri — paid; metabolic-coaching CGM.
• NutriSense — paid; consumer-CGM coaching.
• Lingo (Abbott) — paid; T2-pre-diabetic; Abbott's own CGM-coaching wrap.
• ★ Stelo (OTC, no coaching) — paid (~$99/mo); just the sensor + a clean app; the lower-cost path. See Diabetes & CGM Tools.

Continuous biomarkers (emerging)

• Levels Whole Health (2024) — combines CGM + blood panel.
• Wearable lactate / hydration sensors (in development; nothing widely-shipped in 2026).
• Apollo Neuro / Whoop MG ECG — see Wearables: Oura & Whoop.

DIY / self-host

• ★ Manual CSV import to Notion / Obsidian — track lab results across years; the simplest QS pattern. See Notes & Wiki.
• MyChart's lab feed (US) — most providers expose results via FHIR / Apple Health Records. See Health Records & FHIR.
• Apple Health Records → Apple Health Auto Export — pulls labs out as JSON; usable in Quantified Self pipelines.

What biomarkers actually correlate with longevity / health

The reality check on which markers matter for outcomes (paraphrased from the consensus literature):

• ★ HbA1c, fasting glucose, fasting insulin — metabolic-health markers; HOMA-IR for insulin resistance.
• ★ Lipid panel + ApoB + Lp(a) (often paid extras) — cardiovascular risk; ApoB > LDL-C in cardio-risk literature.
• ★ hsCRP — inflammation; cheap, widely available.
• ★ Vitamin D — common deficiency; inexpensive correction.
• Ferritin / iron — common deficiency in menstruating women / endurance athletes.
• B12, folate — vegan / older populations.
• TSH (Thyroid) — common subclinical issue.
• Testosterone (men > 40 / symptoms) — covered if symptomatic.
• CBC + CMP — broad organ function.

Many "100+ marker" panels include markers with weak evidence (gut peptides, certain hormones in healthy populations). Not all markers are equally meaningful.

Privacy considerations

• Lab data is HIPAA-covered when ordered by a clinician; consumer-only platforms vary.
• Function / InsideTracker / EverlyWell sign BAAs but you grant them broad data use in their TOS.
• Insurance-billed labs flow into MyChart and are private to your providers + you.
• See Health Data Privacy.

Cost / license honesty

• Function Health — ~$500/yr.
• InsideTracker — $200-700 per panel.
• Quest MyChoice / LabCorp Pixel — $50-200 per panel a la carte.
• EverlyWell / LetsGetChecked — $50-200 per kit.
• Levels / Veri / NutriSense — $200-400+/mo (sensor + program).
• Stelo OTC CGM — ~$99/mo.
• Insurance annual labs — typically $0-30 copay.

Pick this if…

• Most comprehensive single annual snapshot: Function Health or InsideTracker.
• Just want labs without coaching: Quest MyChoice / LabCorp Pixel a la carte.
• Want CGM + coaching, T2-curious: Levels or Veri.
• Just CGM, no coaching: Stelo OTC.
• Cheapest reasonable approach: ask your PCP for a comprehensive baseline panel + Stelo for 30 days.
• Privacy-first / DIY tracking: insurance labs → MyChart → personal SQLite via Quantified Self.
