Confirm your initial diagnosis
The confirmation blood test, conducted at least four weeks after the initial testosterone test, verifies the diagnosis of low testosterone. Together, these two tests establish a baseline testosterone level, enabling our doctors to tailor your treatment plan and dosing regimen effectively.
Venous blood tests are considered the gold standard for accuracy, you can select to visit a clinic or book a nurse to come to your home for your blood draw.
