What is this test?
This test measures the level of testosterone in the blood. Testosterone is the main sex hormone (androgen) in men. It is responsible for male physical characteristics. Although it is considered to be a “male” sex hormone, it is present in the blood of both men and women.
 
Sample required
Blood.
 
Patient preparation
Early morning samples are preferred. A woman’s sample should be collected at specific times during her menstrual cycle. Inform the doctor if you are on any medications, or have any allergies or underlying medical conditions before this test.
 
Turn-around time (How long does it take?)
2 Hours.
 
Basis of the Test
Testosterone is mainly produced by special endocrine tissue (the Leydig cells) in the male testicles. It is also produced by the adrenal glands in both males and females and, in small amounts, by the ovaries in females.
