Free Testosterone Test

It is a simple blood test that measures free form of testosterone in the body. It is also called as free T- index. Testosterone is an important hormone secreted in both males and females. In males it is produced in testis and in females it is produced in ovaries. Some amount is also secreted by adrenal glands.

In males testosterone plays a vital role in sexual development. It causes production of sperms, increase in size of genital organs, increase in bone density and muscle mass, deepening in voice and increase sex drive. Its production increases at the time of puberty and gradually decreases as the age advances. In females it is produced in fewer amounts and helps in maintaining hormone balance.

Testosterone secreted in the blood is either bound to proteins such as albumin and sex hormone binding globulin (SHBG) or it is unbound .this unbound form of testosterone is called as free testosterone. This form of testosterone is easily available for various functions in the body.
