Lab Testing — No Doctor Required
Every service on this list lets you order blood work online, pay out of pocket, and get results without a physician’s order. No insurance, no waiting rooms.
This guide maps each service against the Universal Baseline and specialty markers from the Know Your Numbers testing guide — so you know exactly what each service covers and where the gaps are before you order.
For most researchers: Function Health ($365/yr) covers nearly the full Pineland Research baseline with 2 draws/year + clinician review — and just dropped to $1/day. For specialty/oxidative markers (8-OHdG, RBC Glutathione): add Marek Diagnostics. For maximum flexibility without a subscription: Walk-In Lab or Ulta Lab Tests à la carte.

Biological Age
~28 markers total
IGF-1 · Fasting Insulin · HbA1c · LH · FSH · AM Cortisol · Free T4 · Full CBC · Full CMP · DHEA-S · Prolactin · Homocysteine · RBC Magnesium · IL-6 · 8-OHdG · RBC Glutathione
Limited-time 20% off codes available (check site). HSA/FSA eligible. At-home convenience — no draw site required. Best used as a monthly check-in between quarterly or semi-annual full-panel draws. Do not use as your primary protocol baseline — too many critical markers are missing.
At ~$1,200/year (with Tasso+ kit + shipping), Rythm costs over 3× what Function Health charges — but covers roughly half the markers. The value is in monthly frequency for trend tracking, not depth. If you’re running any GH, metabolic, or hormone protocol from the Pineland Research guide, IGF-1 and fasting insulin are non-negotiable markers that Rythm simply doesn’t test.
- Fast 8–12 hours before: Fasting Glucose, HbA1c, Fasting Insulin, Lipid Panel, CMP
- AM Cortisol: Draw before 9 AM — cortisol drops sharply after this window
- Hormones + thyroid: fasting preferred, not strictly required
- Water is fine — coffee, exercise, and stress all skew results
- Draw baseline before starting any research protocol
- Wait 48+ hours after last administration before drawing labs
- Retest at 8 weeks — enough time for measurable changes
- Track trends, not single values
- Estradiol: Always order the “sensitive” or “LC/MS-MS” version — not standard immunoassay (especially for males or anyone on a protocol)
- Magnesium: Order RBC Magnesium — not serum magnesium. They’re different tests entirely.
- CRP: Order high-sensitivity CRP (hs-CRP) — not standard CRP
- Any marker in the Red Flag zone (see Know Your Numbers guide)
- Chest pain, severe fatigue, sudden cognitive changes
- PSA elevation in males over 40
- Any abnormal result you can’t explain — DTC labs are for research, not diagnosis
New York, New Jersey, Rhode Island, and Massachusetts restrict certain DTC lab tests. Function Health is not available in RI, HI, or Puerto Rico. Walk-In Lab has test restrictions in NY, NJ, RI, and MA. Mito Health notes pricing may vary in NY, NJ, and RI. If you’re in one of these states, verify availability before purchasing.
