Free Androgen Index - Book Test at Low Cost

The Free Androgen Index (FAI) is a laboratory test used to evaluate the level of androgens in the body. Androgens are the hormones that are important for the development of male characteristics, such as muscle growth, deepening of the voice, and facial hair.

The FAI is calculated by dividing the total testosterone level by the sex hormone-binding globulin (SHBG)level and multiplying the result by 100. The result is expressed as a percentage and provides an estimate of the amount of biologically active or free, testosterone in the bloodstream.

It is usually combined with other tests, such as the measurement of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), to obtain a more accurate diagnosis.

Why is the Free Androgen Index done?

The Free Androgen Index (FAI) is done to measure the levels of androgens in the body, particularly testosterone. It is often ordered when there is suspicion of an androgen-related disorder, such as:

Polycystic ovary syndrome (PCOS) - It is a hormonal disorder that affects women and can cause menstrual irregularities, acne, excess hair growth, and infertility.

Androgen excess in men - a condition that can lead to symptoms such as infertility, erectile dysfunction, and decreased muscle mass.

Hypogonadism - a condition that occurs when the body doesn't produce enough testosterone, which can lead to delayed puberty and other symptoms.

Hirsutism - excessive hair growth in women, often caused by high androgen levels.

Monitoring of testosterone therapy - in cases where testosterone replacement therapy is used to treat low testosterone levels in men, the FAI may be used to monitor the effectiveness of the treatment.

A low FAI value may indicate a deficiency of androgens, which can lead to conditions such as hypogonadism or delayed puberty in males.
