Lab Testing Guide
You can not optimize what you do not measure. Bloodwork is the most actionable data you can get for health optimization.
Why Get Tested?
Catch Problems Early
Many chronic conditions are detectable through bloodwork 5–10 years before symptoms appear. Early detection means early intervention.
Personalize Your Stack
Instead of guessing which supplements you need, lab results reveal actual deficiencies and imbalances unique to your body.
Track Your Progress
Regular testing creates a longitudinal data set showing how your interventions (diet, exercise, supplements) are actually working.
Key Markers to Track
These biomarkers provide the most actionable information for health optimization. Request them by name at your next blood draw.
Complete Blood Count (CBC)
Every 6–12 monthsBaseline assessment of immune function, oxygen-carrying capacity, and overall blood health.
Comprehensive Metabolic Panel (CMP)
Every 6–12 monthsEvaluates kidney and liver function, blood glucose, and electrolyte balance.
Lipid Panel (Advanced)
Every 6–12 monthsApoB and Lp(a) are better predictors of cardiovascular risk than standard LDL alone.
HbA1c & Fasting Insulin
Every 6 monthsEarly detection of insulin resistance and metabolic dysfunction—often years before diabetes diagnosis.
Vitamin D (25-OH)
Every 6 months (or seasonally)Deficiency is extremely common and linked to immune function, mood, and bone health.
Thyroid Panel (TSH, Free T3, Free T4)
AnnuallyThyroid dysfunction is underdiagnosed and impacts energy, weight, and cognition.
Testosterone (Total & Free) / Estradiol
Every 6–12 monthsHormonal optimization is central to energy, body composition, and mood in both sexes.
hs-CRP
Every 6–12 monthsHigh-sensitivity C-reactive protein measures systemic inflammation—a root cause of chronic disease.
