Bloodwork Guide
Understanding your bloodwork is the foundation of health optimization. Learn what each marker means, why conventional "normal" ranges are not the same as optimal, and how to interpret your results for peak performance and longevity.

Optimal vs. "Normal" Ranges
Why your doctor says you're fine when you feel terrible
Conventional reference ranges are derived from the average of everyone who walks into a lab — including the sick, the sedentary, the obese, and the elderly. Being "within range" means you're not in the bottom or top 2.5% of this population. It does not mean you're healthy.
Optimal ranges represent where research shows the lowest disease risk, highest energy, best cognitive function, and greatest longevity. The difference between "normal" and "optimal" can be the difference between surviving and thriving.
For example, conventional medicine considers a testosterone level of 264 ng/dL "normal" in a 35-year-old man. That same level in a man's grandfather would have been considered a medical emergency. The ranges haven't changed — the population has gotten sicker, dragging the "normal" range down with it.
Wait until markers are outside the wide reference range, then prescribe medication to push them back into range.
Identify suboptimal trends early and intervene with lifestyle, nutrition, and targeted supplementation before disease develops.
Target the narrow optimal range where research shows peak performance, lowest disease risk, and maximum longevity potential.
Recommended Testing Schedule
Baseline Panel
Before starting any protocolComplete metabolic panel, full hormone panel, CBC, lipids, inflammation markers (hsCRP, homocysteine), vitamin D, B12, ferritin, thyroid (TSH, Free T3, Free T4)
This is your starting point. You cannot optimize what you don't measure.
Follow-Up Panel
6–8 weeks after starting a protocolTargeted markers related to your protocol (e.g., hormones for TRT, metabolic markers for GLP-1, liver/kidney for any new compound)
Early check to ensure your body is responding well and no adverse effects.
Optimization Panel
Every 3–4 monthsFull panel repeat with focus on markers that were previously suboptimal. Track trends over time.
Trends matter more than single data points. Look for directional improvement.
Annual Comprehensive
Once per yearEverything above plus: insulin, HOMA-IR, advanced lipid panel (NMR), thyroid antibodies, sex hormone panel, tumor markers if age-appropriate
Your annual deep dive. Compare year-over-year to catch slow-developing issues.
