Understanding Your Longevity Labs
A comprehensive longevity lab panel is the foundation of any evidence-based longevity medicine program. But most people have no idea what to ask for, what the numbers mean, or how to interpret them in context. Dr. Kamen walks you through the key biomarkers, what optimal ranges look like, and how to use your results to guide interventions.
Why Standard Lab Work Isn't Enough
Most conventional medicine uses "reference ranges" that represent the average range of a sick population — not the range associated with optimal health or longevity. A panel that flags nothing as "abnormal" can still reveal significant opportunities for intervention. [1]
Longevity medicine uses "optimal ranges" — the biomarker levels associated with the lowest disease risk and highest function in the peer-reviewed literature. These are often narrower and more aggressive than standard lab reference ranges.
The Core Longevity Panel
A comprehensive longevity lab panel at LiveNow Longevity includes the following biomarker categories:
- Metabolic markers: Fasting glucose, HbA1c, insulin, HOMA-IR (insulin resistance), lipid panel (total cholesterol, LDL, HDL, triglycerides, lipoprotein(a))
- Inflammatory markers: hs-CRP, IL-6, TNF-alpha, fibrinogen — these low-grade inflammation markers are more predictive of cardiovascular risk than LDL alone. [2]
- Hormones: Total testosterone, free testosterone, estradiol, progesterone, DHEA-S, SHBG, cortisol (morning and evening)
- Thyroid: TSH, free T3, free T4, reverse T3
- NAD+ panel: NAD+ precursor levels and metabolites
- Nutrient markers: Vitamin D (25-OH), B12, folate, magnesium, zinc, selenium
- Oxidative stress: Glutathione, GGT, uric acid
- Body composition: DEXA scan for visceral fat, lean mass, and bone density
- Telomere testing: Optional — measures average telomere length in leukocytes as a proxy for biological age
Understanding Your HbA1c in Context
Standard medicine uses HbA1c > 6.5% as diabetes diagnosis. But epidemiologic data consistently show that HbA1c > 5.5% is associated with accelerated cardiovascular and cognitive decline. [3]
At LiveNow Longevity, we use an optimal HbA1c range of < 5.4% as a longevity target. This frequently requires nutritional and exercise intervention — and occasionally pharmaceutical support — but the evidence base for this target is strong.
hs-CRP: The Overlooked Cardiovascular Risk Marker
High-sensitivity C-reactive protein (hs-CRP) is one of the most robust independent predictors of cardiovascular events in otherwise healthy individuals. A landmark study in the New England Journal of Medicine found that individuals with hs-CRP in the highest quartile had a 3x increased risk of myocardial infarction compared to those in the lowest quartile — independent of cholesterol levels. [4]
Optimal hs-CRP on a longevity panel is < 1.0 mg/L. Many patients are unaware they have elevated hs-CRP until it is specifically tested.
Key Takeaways
- Standard reference ranges represent the average sick population — longevity medicine uses optimal ranges tied to disease risk reduction
- A comprehensive longevity panel includes metabolic, inflammatory, hormonal, and oxidative stress biomarkers
- hs-CRP and HbA1c are powerful but underutilized markers that respond to lifestyle and pharmacologic intervention
- Lab results should guide therapy — supplements, peptides, hormones, and medications should never be started without baseline data
- Dr. Kamen reviews all labs in detail during a 60-minute consultation
Common Questions
How often should I get longevity labs done?
Dr. Kamen typically recommends comprehensive labs annually, with key metabolic and inflammatory markers checked every 6 months during active optimization programs.
Will insurance cover longevity lab panels?
Many individual markers are covered by insurance when medically indicated. Panels ordered as "wellness" or "preventive" may have limited coverage. We provide itemized superbills to support insurance reimbursement.
Do I need to fast before the labs?
Yes — fasting for 10-12 hours before blood draw is required for accurate glucose, insulin, lipid panel, and HOMA-IR results.
What is DEXA scan for body composition?
DEXA (dual-energy X-ray absorptiometry) provides precise measurement of visceral fat, lean mass, and bone density — far more accurate than BIA scales or BMI alone. It is used to track changes over time during longevity programs.
Understanding your biomarkers is the first step to optimizing them. Schedule a consultation to discuss comprehensive longevity lab testing, or learn more about our longevity medicine programs.
