Reference range
Reference ranges vary by lab, age and sex. Your own lab report carries the authoritative range, and your clinician reads it with you.
Why it matters
Hematocrit is the safety marker on any testosterone protocol. Testosterone stimulates erythropoiesis; persistently elevated hematocrit increases blood viscosity and warrants protocol adjustment, hydration review, and — when needed — therapeutic phlebotomy. REVRCEL members on hormone protocols have hematocrit re-read every quarter.
How REVRCEL clinicians read it
The protocol-safety marker on TRT. Quarterly re-read; act on persistent elevation.

Common questions
Why does TRT raise hematocrit?
Testosterone stimulates red blood cell production (erythropoiesis). It is an expected effect that needs monitoring, not necessarily a reason to stop.
