A testosterone levels test measures the amount of the hormone testosterone in a sample of your blood. Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs.
A testosterone levels test may be used with other tests to help your provider find the cause of abnormal testosterone levels.
