Best Bloodwork for Longevity

The Comprehensive Panel · 9 min read

Most annual physicals check a handful of basic markers that only catch disease in late stages. A longevity-focused blood panel goes deeper — detecting metabolic dysfunction, cardiovascular risk, and inflammation years before symptoms appear. Here’s the definitive panel.

Key Takeaways

  • Standard annual bloodwork misses the most important longevity markers.
  • A comprehensive longevity panel includes 20-25 markers across metabolic, cardiovascular, inflammatory, and hormonal domains.
  • ApoB, fasting insulin, and hs-CRP are the most underordered yet most predictive markers.
  • Test every 6-12 months for maintenance, every 3 months during active optimization.
  • Always test fasted, same time of day, same lab for consistent comparisons.

Why Standard Panels Fall Short

A typical annual physical includes a basic metabolic panel, lipid panel, and CBC. While useful, these miss critical markers. Standard lipid panels report LDL cholesterol but not ApoB — the actual particle driving atherosclerosis. They check fasting glucose but not fasting insulin — which becomes abnormal 10-15 years before glucose rises. They rarely include inflammatory markers, hormonal panels, or nutritional status. A longevity-focused panel fills these gaps, giving you a complete picture of your biological health trajectory.

Tier 1: The Essential Longevity Panel

These markers should be tested at minimum every 6-12 months. They cover the most critical health domains:

  • Fasting glucose: Target 72-85 mg/dL — your basic metabolic checkpoint
  • HbA1c: Target < 5.4% — 3-month average of blood sugar control
  • Fasting insulin: Target 2-6 µIU/mL — the earliest metabolic dysfunction marker
  • ApoB: Target < 80 mg/dL (< 60 for high risk) — the #1 cardiovascular risk predictor
  • Lipid panel (Total, LDL, HDL, Triglycerides): Triglyceride:HDL ratio < 1.5 is ideal
  • hs-CRP: Target < 1.0 mg/L — systemic inflammation marker
  • Vitamin D (25-OH): Target 50-80 ng/mL — impacts nearly every organ system
  • CBC with differential: General health screen and immune function
  • Comprehensive metabolic panel (CMP): Kidney function, liver enzymes, electrolytes

Tier 2: Advanced Longevity Markers

These provide deeper insight and are especially valuable if you’re actively optimizing or have specific concerns:

  • Lp(a): Genetic cardiovascular risk factor — test once (it doesn’t change much). Elevated Lp(a) requires more aggressive ApoB management
  • Homocysteine: Target < 10 µmol/L — elevated levels indicate B-vitamin deficiency and cardiovascular risk
  • Omega-3 Index: Target 8-12% — measures red blood cell EPA/DHA content
  • Magnesium RBC: Target 5.0-6.5 mg/dL — serum magnesium misses most deficiency
  • Ferritin: Target 40-150 ng/mL — both too low (anemia) and too high (iron overload) are problematic
  • Thyroid panel (TSH, free T3, free T4): Target TSH 0.5-2.5 mIU/L for optimal function
  • DHEA-S: An adrenal hormone that declines with age — marker of biological aging

Tier 3: Hormonal and Specialty Markers

These are most relevant for specific populations or concerns:

  • Testosterone (total + free) and SHBG: Essential for men over 35 and women with hormonal symptoms
  • Estradiol and progesterone: Important for women in perimenopause and beyond
  • Cortisol (AM): Elevated levels indicate chronic stress and HPA axis dysfunction
  • IGF-1: Growth factor linked to both muscle health and cancer risk — context matters
  • Uric acid: Target 5-6 mg/dL — elevated levels predict metabolic syndrome and gout
  • GGT: Liver enzyme that’s a sensitive marker for metabolic dysfunction and oxidative stress
  • HbA1c + fructosamine together: Fructosamine shows 2-3 week glucose average, complementing HbA1c’s 3-month window

How to Order and Interpret

Getting comprehensive bloodwork is easier and more affordable than most people think:

  • Ask your doctor: Request specific markers by name — many doctors will order them if you ask
  • Direct-to-consumer labs: InsideTracker, Marek Health, and Quest/LabCorp Direct offer panels without prescriptions
  • Cost: A comprehensive longevity panel costs $200-500 through direct-to-consumer services vs. potentially thousands through insurance billing
  • Always test fasted (12-14 hours), morning (before 10am), well-hydrated, and after a normal night’s sleep
  • Avoid intense exercise 24-48 hours before testing — it transiently affects many markers
  • Compare your results to optimal ranges, not just standard reference ranges

Building Your Testing Schedule

A practical testing schedule balances information gathering with cost and convenience:

  • Month 0: Full comprehensive panel (Tier 1 + Tier 2) — your baseline
  • Month 3: Retest any markers that were out of range + markers affected by new interventions
  • Month 6: Repeat Tier 1 panel to track trends
  • Month 12: Full comprehensive panel again — your annual check-in
  • Lp(a): Test once — it’s genetically determined and rarely changes
  • Hormones: Test annually unless actively managing a hormonal issue
  • Log everything in a spreadsheet with dates, values, and notes about what changed between tests

The Bottom Line

A comprehensive longevity panel goes far beyond standard bloodwork. Prioritize fasting insulin, ApoB, hs-CRP, and vitamin D alongside standard markers. Test every 6-12 months, track trends, and use the data to guide your interventions.
