🩸 Blood Work

Got my first follow-up lab results—how should I compare them to my baseline?

Asked in r/Testosterone · Answered by the HeydayMD team ·

I just got my follow-up lab work back after starting TRT and I'm not entirely sure which numbers matter most when looking back at my pre-treatment baseline. How do patients typically evaluate changes in these specific biomarkers over time?

The short answer

When reviewing follow-up labs, the primary focus is typically on how your testosterone levels and key safety markers have shifted compared to your pre-treatment baseline. Comparing these figures helps evaluate how effectively your protocol is absorbing and whether secondary parameters like red blood cell counts remain within a safe, manageable range. Because every individual metabolizes testosterone differently, interpreting these shifts requires looking at the complete picture rather than isolated numbers. It is always recommended to review your specific results and any potential protocol adjustments directly with your licensed prescriber.
