Advanced Blood Panels (InsideTracker, Marek Health, Function Health) — Diagnostics & Biomarker Testing
Comprehensive direct-to-consumer blood testing services providing 50-100+ biomarker panels with AI-driven personalized recommendations for longevity optimization.
Overview
Direct-to-consumer comprehensive blood testing platforms provide access to extensive biomarker panels without requiring a physician's order. InsideTracker tests 43 biomarkers and uses an algorithm trained on 2,800+ peer-reviewed studies to provide personalized dietary and lifestyle recommendations. Marek Health offers clinician-ordered panels including testosterone, thyroid, metabolic, inflammatory, and cardiovascular markers at below-market prices, with physician consultation. Function Health (co-founded by Dr. Mark Hyman) provides 110 biomarkers twice yearly for $499/year. Peter Attia's Early Medical program offers similar comprehensive testing. Key biomarkers beyond the standard metabolic panel include: ferritin (iron storage), hsCRP (inflammation), homocysteine, DHEA-S, free testosterone (men), IGF-1, 25-OH vitamin D, ApoB, Lp(a), HbA1c, and thyroid panel (TSH, free T3, free T4). Having comprehensive baseline data enables early detection of metabolic trends years before clinical disease develops.
Indications
- Comprehensive health baseline establishment
- Nutritional deficiency identification (Vitamin D, B12, iron, magnesium)
- Hormonal balance assessment (testosterone, thyroid, cortisol, DHEA)
- Inflammatory burden quantification (hsCRP, IL-6, fibrinogen)
- Longevity intervention response monitoring
- Early metabolic disease detection
Mechanism of Action
Comprehensive multi-marker panels reveal patterns and interactions between metabolic, hormonal, inflammatory, and nutritional systems that single markers cannot — metabolic syndrome requires simultaneous assessment of glucose, insulin, lipids, and inflammation
Dosing
| Compound | Dose | Frequency | Notes |
|---|---|---|---|
| Comprehensive Panel (Function Health) | Fasting blood draw, 110 biomarkers | 2x annually | $499/year membership; includes physician interpretation |
| Marek Health Panel | Clinician-ordered blood draw | Quarterly or annually depending on protocol | Highly customizable panels; physician consultation available; typically $200-600/panel |
Evidence Grade
GRADE B
Safety & Contraindications
- Standard blood draw risks (bruising, lightheadedness)
- Direct-to-consumer results without physician context can cause unnecessary anxiety
- Out-of-range values require physician evaluation — do not self-treat without consultation
- Some tests require fasting (glucose, triglycerides, insulin); others do not
