The Free Androgen Index (FAI) is a valuable indicator in assessing androgen levels in the body, particularly for diagnosing conditions related to hormone imbalances.
Androgens are a group of hormones, including testosterone, that play a critical role in the development of male characteristics, though they are present in both men and women. The FAI blood test pune is a blood test that helps measure the levels of free (unbound) testosterone, which is biologically active in the body. The Free Androgen Index (FAI) is a calculation used to estimate the concentration of free testosterone in the bloodstream. The formula for calculating the Free Androgen Index is:
FAI = (Total Testosterone ÷ Sex Hormone Binding Globulin [SHBG]) x 100
The Free Androgen Index blood test is performed to assess free testosterone levels, which is essential for identifying hormone-related disorders. This test is often recommended when there are symptoms of hormone imbalance, such as infertility, irregular menstrual cycles, or signs of androgen excess, such as acne, hair loss, or excessive hair growth (hirsutism) in women. This blood test is quick and simple. Blood is drawn from a vein in the arm, and the sample is then analyzed to determine the levels of testosterone and SHBG, which are used to calculate the FAI.
The free androgen index range varies depending on gender and age. Normal ranges help determine if a person has healthy levels of free testosterone or if there is a hormonal imbalance.
1] For men, a typical free androgen index falls between 30-150.
2] For women, the normal range is significantly lower, usually around 0.5-7.
It's important to note that the reference range for the FAI can vary slightly depending on the laboratory that performs the test, so it’s crucial to interpret results with the help of a healthcare professional.
Women who present with signs of high androgen levels, such as hirsutism or acne, often undergo the free androgen index test in Delhi. Elevated FAI levels in women may indicate conditions like:
1] Polycystic Ovary Syndrome (PCOS)
2] Adrenal Hyperplasia
3] Ovarian Tumors (though rare, they can lead to excessive androgen production)
4] Hirsutism (excessive facial or body hair growth)
For men, the free androgen index blood test Delhi is useful in evaluating symptoms of androgen deficiency or excess. Low FAI levels in men may be linked to conditions such as:
1] Hypogonadism: A condition where the testes produce insufficient testosterone, leading to symptoms like reduced muscle mass, fatigue, and a decrease in sexual desire.
2] Andropause: A gradual decrease in testosterone levels with age, sometimes referred to as "male menopause," can result in decreased energy, mood changes, and lower libido.
3] Infertility: FAI testing can help determine if low testosterone levels are contributing to male infertility.
