The essentials (annually or every 2 years)

  • apoB: definitive lipid marker; often <$50.
  • Lp(a): once-in-a-lifetime; ~$50–100.
  • HbA1c: metabolic status; ~$25.
  • Fasting insulin: insulin resistance; ~$25.
  • hs-CRP: inflammation; ~$25.
  • Comprehensive metabolic panel (CMP): liver, kidney, glucose, electrolytes; included in standard bloodwork.
  • Complete blood count (CBC): haemoglobin, ferritin, WBC; standard.
  • TSH and free T4: thyroid; ~$50 combined.
  • 25-hydroxy vitamin D: ~$50; only if suspected deficient.

Once-per-decade or as-indicated

  • CAC score: $100–200 at most imaging centres; profoundly reclassifies risk.
  • DEXA scan: body composition + bone density; $50–200.
  • VO2max: submax estimate on a wearable is often free.

Skip (for most healthy adults)

  • Comprehensive 100-marker "longevity panels" (Function Health, InsideTracker) unless you value the concierge experience — the incremental biomarkers add little actionable signal.
  • Single-timepoint epigenetic-age tests (variance dominates trend for one reading).
  • Heavy-metal panels without exposure history.
  • "Food sensitivity" IgG panels (not validated).
