A Free Androgen Index (FAI) is a ratio calculated from a blood test that measures testosterone levels, helping to assess whether androgen levels are abnormal.

Both men and women produce male hormones known as androgens, which includes testosterone. This hormone plays a crucial role during puberty, aiding in the transition from childhood to adulthood. However, testosterone levels can decline with age, leading to health issues for both genders.

In females, excess androgens can lead to increased body and facial hair, while low levels may cause fatigue and reduced libido. In males, testosterone is crucial for developing male traits; low levels can result in weakness, muscle loss, and decreased sexual interest.

A testosterone test analyses total testosterone, free testosterone, and a protein called sex-hormone binding globulin (SHBG). The FAI specifically measures testosterone in the blood and compares the total testosterone levels to SHBG levels in the body.

This test is particularly significant in women experiencing excessive body or facial hair to determine the cause. Abnormal hair growth could indicate conditions such as an ovarian tumour or polycystic ovarian syndrome (PCOS).

You can schedule the FAI test to check your androgen levels in a city like Bangalore with the convenience of home-testing.
