TRT Blood Work: The Labs & Monitoring Schedule
The baseline and ongoing panel every man on TRT should run — testosterone, estradiol, hematocrit, PSA, lipids — and how often to check them.
What blood tests do I need on TRT and how often?
- •Baseline panel typically includes total + free testosterone, estradiol, CBC (hematocrit), PSA, lipids, and often LH/FSH.
- •Hematocrit is the most important safety marker — TRT can thicken the blood (polycythemia); it's checked regularly.
- •Levels are usually rechecked at ~6-8 weeks after starting or changing dose, then periodically (often every 6-12 months once stable).
- •PSA is monitored because TRT can raise it; a meaningful rise warrants urology evaluation.
- •A provider that doesn't require ongoing labs is a red flag, not a convenience.
