New to reading lab reports? Start with our guide to reading a blood test report
Testosterone is a hormone that shapes sex traits, muscle, and drive in both men and women.
A Total Testosterone result gives you a single figure for this key sex hormone in your blood. Doctors read it as one part of a wider picture, next to your symptoms and other results.
Also known as: Testosterone total, T, Serum testosterone, Total T
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.
