If you use testosterone therapy, you're followed by a doctor with blood tests. That isn't a formality: it helps keep the treatment safe. Often-looked-at values are your testosterone, your haematocrit and haemoglobin, your oestradiol and your PSA.
The frequency and approach are set by your treating doctor. This article explains why those values matter, not how often you should test.
Why is it monitored?
Testosterone therapy affects more than just your testosterone. Your body can make more red blood cells, for example, seen in a rising haematocrit. By following along, your doctor can adjust in time. The aim is a safe balance, tailored to you.
Which values and why?
Testosterone shows whether you're in a suitable range. Haematocrit and haemoglobin indicate whether your blood isn't getting too thick. Oestradiol belongs to the hormonal balance, and PSA is often followed as a prostate value. Your doctor assesses the whole, not one number.
What does this mean for you?
Follow your treating doctor's appointments; stopping or adjusting the dose on your own isn't part of that. To understand how a path begins, see before starting TRT and the pillar male hormonal health.
Getting started
Between check-ups, the Men's Hormones panel or the Testosterone Panel can give a picture to discuss with your doctor. It doesn't replace your doctor's supervision.
