HRT monitoring — labs to get and where

5 min read

This guide is harm-reduction information. It is not medical advice. Lab results require interpretation, and the safest interpretation comes from a clinician.

Without monitoring, HRT is guesswork. Lab work tells you whether your hormones are at safe levels, whether your liver is handling the medication, and whether anything quiet is going wrong. Skipping labs is the most common mistake people make on self-administered HRT.

What labs to get

For trans-feminine HRT (estrogen + antiandrogen)

TestWhy it mattersTarget
Estradiol (E2)Confirms estrogen is working200–300 pg/mL
Testosterone (total)Confirms antiandrogen is working<50 ng/dL (suppressed to female range)
ProlactinCPA elevates prolactin; very high prolactin suggests dose reduction<25 ng/mL ideally
Liver function (ALT, AST, GGT)CPA and bicalutamide are hepatotoxicWithin normal range
PotassiumOnly relevant if on spironolactone3.5–5.0 mEq/L
Lipid panelYearly baselineWithin normal range
Brain MRI (when indicated)If on long-term CPA and developing headaches, vision changes, or other neurological symptoms — rule out meningiomaNon-negotiable when symptomatic

For trans-masculine HRT (testosterone)

TestWhy it mattersTarget
Testosterone (total)Confirms dose is correct400–700 ng/dL
Estradiol (E2)Should drop naturally; very high E2 may suggest aromatization<50 pg/mL
Hematocrit / hemoglobinTestosterone increases red blood cell count; high hematocrit raises clotting risk<54% hematocrit
Lipid panelTestosterone affects cholesterolWithin normal range
Liver functionYearly baselineWithin normal range

When to test

If you change a dose or add a medication, retest in 6–8 weeks.

How to time the blood draw

Hormone levels vary throughout the day. To get a meaningful reading:

A note on community lab interpretation

The collective has people who have read their own labs for years and can help interpret yours if you share them. We are not doctors. We can flag obvious problems and suggest dose adjustments based on community knowledge, but we cannot diagnose you. If something looks seriously wrong on your labs, please see a doctor — even an internist who is not familiar with HRT can interpret liver function and red blood cell counts.

If you would like to share lab results for community feedback, reach out via the community channel. We will never store or share them.
