Testosterone test
Also called: total testosterone level, low T test
What it means
A testosterone test is a blood test that measures the amount of testosterone in your body, usually reported as "total testosterone." It helps check for low testosterone, sometimes called "low T."
Testosterone helps maintain bone density in both men and women, so low levels can contribute to bone loss over time.
A testosterone test is a simple blood draw, often done in the morning when levels are highest. It measures total testosterone, and sometimes free testosterone, which is the portion not bound to proteins like sex-hormone-binding globulin. Doctors use it to evaluate symptoms like low energy, reduced muscle mass, low libido, or unexplained bone loss.
While testosterone is often thought of as a male hormone, it matters for bone health in both sexes. It supports bone formation and helps maintain muscle mass, which in turn supports bone through everyday loading. Low testosterone, sometimes linked to aging, certain medications, or conditions affecting the testes or pituitary gland, is one of several causes doctors consider when someone has unexplained osteoporosis or low bone density.
If a test shows low testosterone, your doctor will look at the full picture, including symptoms, other hormone levels, and your overall health, before deciding on next steps. Treatment decisions, including whether testosterone replacement therapy might be appropriate, belong to your doctor, since this involves weighing benefits and risks specific to your situation.
