How old are you?
Age affects which markers matter most for your health.
Functional Blood Panels
What We Test & Why It Matters
Our panels go beyond standard disease screening. Every marker is chosen to give you actionable data about your metabolic health, hormones, and body composition.
Basic Panel — $250
Metabolic, thyroid, inflammation, vitamins
Our comprehensive metabolic panel covers the markers most doctors skip — fasting insulin, full thyroid (TSH, Free T3, Free T4), CRP inflammation, vitamin D, B12, and HbA1c alongside a complete metabolic and lipid panel.
Note: Testosterone and sex hormones are NOT included. These require the hormone add-on.
Hormone Add-On — +$75
Testosterone, estradiol, progesterone & more
A separate hormone panel covering total and free testosterone, estradiol (E2), progesterone, DHEA-S, LH, FSH, and SHBG. Required for anyone with symptoms of hormonal imbalance, low libido, mood issues, or fatigue.
Why separate? Hormone panels require different processing and interpretation — they cannot be bundled into the basic draw.
InBody Scan — $99
Body fat, muscle mass, visceral fat
Clinical-grade body composition analysis using bioelectrical impedance. Measures body fat percentage, segmental lean mass by body part, visceral fat level, and total body water. Far more accurate than BMI or home scales.
VO2 Max & RMR — $199
Cardiovascular fitness + true calorie burn
VO2 Max is the gold standard for cardiovascular fitness and the strongest predictor of longevity. Your Resting Metabolic Rate (RMR) test reveals exactly how many calories your body burns at rest — the most accurate calorie target available.
What is a functional blood panel?
A functional blood panel goes beyond standard disease screening to assess how your body is actually performing — measuring metabolic rate, hormonal balance, inflammation, and nutritional status to identify optimization opportunities before problems develop.
Why is testosterone not in the basic panel?
Testosterone, estradiol, progesterone, DHEA-S, and SHBG require a separate hormone panel. Our $250 basic panel covers metabolic, thyroid, and inflammatory markers. The hormone add-on (+$75) is required for a complete hormonal picture.
How is this different from my doctor's bloodwork?
Standard doctor panels check for disease markers. Our panels are designed for metabolic optimization — including fasting insulin, full thyroid (TSH, Free T3, Free T4), CRP, and vitamin D that most routine panels skip.
Do I need to fast before my blood draw?
Yes — we recommend fasting for 10–12 hours before your blood draw for accurate fasting glucose, insulin, and lipid results. Water is fine. Schedule your appointment in the morning for easiest compliance.
What is a Resting Metabolic Rate (RMR) test?
An RMR test measures exactly how many calories your body burns at rest using indirect calorimetry. It's the most accurate way to set calorie targets for weight loss or maintenance — far more precise than any online calculator or formula.
