TRT starts with blood work that measures total testosterone, drawn in the morning and usually confirmed on a second draw, along with related markers such as free testosterone, LH and FSH, estradiol, a complete blood count for hematocrit, PSA for men of appropriate age and a metabolic panel. Your provider chooses the exact panel based on your history.
What this means for you
Each test answers a question. Two morning testosterone levels confirm the diagnosis rather than catching a single low reading. LH and FSH show whether the problem sits in the testes or in the pituitary. Hematocrit, PSA, lipids and liver values establish a safety baseline, because testosterone therapy can raise red blood cell counts and needs prostate monitoring. The same labs are repeated after you start so the provider can see levels and safety markers, not just symptoms.
How it works at Biotech Lifestyle
Your provider tells you which labs are required and how to get them drawn, reviews the results with you in the visit and sets the follow-up lab schedule. Recent results from your own doctor can often be used if they are complete.
