Frequently Asked Questions

The FAI test measures the ratio of total testosterone to sex hormone-binding globulin (SHBG) to estimate free testosterone levels.

It is recommended for individuals with suspected polycystic ovary syndrome (PCOS), androgen excess, or infertility.

A blood sample is tested for testosterone and SHBG levels to calculate the FAI.

  • High FAI: Suggests androgen excess, commonly seen in PCOS.
  • Low FAI: Indicates reduced testosterone levels, possibly due to hypogonadism.

Yes, obesity, stress, and medications can influence androgen levels.
