The testosterone test measures the amount of testosterone, the male hormone, in the blood. However, this hormone is produced by both men and women.

This testosterone test measures the total amount of testosterone found in the blood. A large amount of the testosterone in the blood is bound to a protein called sex hormone binding globulin (SHBG). But another test which measures only the free testosterone in the blood is available. This test for free testosterone isn’t always accurate.

How is a testosterone test done?

A healthcare provider will take a blood sample from your vein. The best time for collecting the blood sample is from 7a.m to 10 a.m. You might need a second sample collection to confirm the result if the initial result was lower than expected.
