Blood markers to test

Test key cardiovascular, metabolic, inflammatory, organ-function, and hormone markers.

• Recommended markers: ApoB, LDL cholesterol, uric acid, fasting insulin, HOMA-IR, iron, hsCRP, GGT, and creatinine. 1 2
• Hormone markers: IGF-1, testosterone, free testosterone, estradiol, DHT, SHBG, cortisol, progesterone, and prolactin. 3
• Timing and interpretation: Measure cortisol in the morning while fasted; creatinine can be elevated with creatine use or hard exercise, so consider those when interpreting the result. 4
• For women: Keep cycle timing consistent; a mid-follicular or mid-luteal test is suggested. Mid-luteal testing is about five to seven days before the next period. 5 6
