Testosterone, Free (Indirect) With Total Testosterone, LC/MS-MS
This test is mostly done in men only and it measures the free testosterone and the testosterone that is bound to SHBG and albumin.
Testosterone is one of the main sex hormones (androgens) that are found in men. Although mostly a “male” sex hormone, it is also found in small amounts in women. Testosterone is responsible for the development of secondary sexual characteristics in males, and the virilization in females. In the body, testosterone is either bound to sex hormone binding globulin (SHBG), albumin or free. A total testosterone test is mostly done in men only and it measures the free testosterone and the testosterone that is bound to SHBG and albumin.
This test is performed in following conditions such as:
• Delayed or early puberty in boys
• Erectile dysfunction in men
• Decreased sex drive in men and women
• Hypothalamus or pituitary disorders
• Infertility in men and women
• Testicular tumors in men
• Hirsutism and virilization in girls and women
