Which blood tests and checkups are needed during testosterone therapy?

Before treatment, your physician needs to confirm low testosterone and check whether therapy is safe for you. Testing commonly includes repeat testosterone measurements and a complete blood count. The blood count includes hematocrit, which shows how much of your blood is made up of red blood cells.

Testosterone can raise red blood cell levels too much. This may increase health risks and require a dose change, a pause in treatment, or further evaluation. Do not try to manage an abnormal result on your own, including by arranging blood donation instead of follow-up care.

During treatment, hormone testing helps guide dosing. The timing of the blood draw matters because levels can change after each dose. Your physician should tell you when to have blood drawn for your specific medication form.

Follow-up also includes blood pressure, side effects, and a review of symptoms. Prostate testing may be discussed based on age and risk. Keep scheduled visits and lab appointments, even if you feel well.
