What is a Free Androgen Index Test in Gurugram ?
What is Free Androgen Index?
The Free Androgen Index (FAI) estimates the amount of biologically active androgen in the blood. It is calculated from total testosterone and the amount of sex hormone binding protein. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.
What does Free Androgen Index measure?
Active androgens influence hair growth, acne, menstrual cycles, and sexual function. Measuring FAI helps detect androgen excess or deficiency. Doctors use it alongside symptoms and other hormone tests to diagnose conditions like polycystic ovary syndrome, hirsutism, infertility, and certain tumors. It also helps monitor response to treatment.
What symptoms suggest Free Androgen Index may be needed?
A doctor may recommend Free Androgen Index when a patient reports irregular or absent menstrual periods, unexplained abdominal weight gain, excessive facial or body hair (hirsutism), acne unresponsive to treatment, mood changes, low libido, and difficulty conceiving. GetVisit makes testing convenient in Gurugram, with lab slots and home collection in Sushant Lok, Sohna Road, and nearby areas.
How is Free Androgen Index performed?
At a GetVisit-partnered lab in Sushant Lok or Sohna Road, Gurugram, a certified phlebotomist cleans the inner elbow, locates a vein, and draws the required blood (typically 5 to 10 mL). The procedure takes 3 to 5 minutes. You feel a brief pinch at insertion and mild pressure during collection, then can eat, drive, and resume all activities immediately afterwards.
How accurate is Free Androgen Index?
Results are analytically reliable because GetVisit's Gurugram logistics network maintains proper cold-chain transport from your Sushant Lok or Sohna Road collection point to the processing lab, preserving sample integrity. NABL independently audits quality control at regular intervals.
Are there any risks to Free Androgen Index?
Beyond a brief pinch, Free Androgen Index carries almost no risk. Keep the arm relaxed during the draw, press gently on the site afterwards, and avoid heavy lifting with that arm for about an hour.
Did you know?
The normal free androgen index (FAI) is generally considered below about 4–5% (FAI = total testosterone [nmol/L] ÷ SHBG [nmol/L] × 100).

Why Take a Free Androgen Index Test in Gurugram ?
When does a doctor order Free Androgen Index?
Free Androgen Index is often ordered as part of an endocrine or reproductive hormone panel when patients have symptoms like excess hair, acne, irregular periods, infertility, low libido, or unexplained virilization. It helps diagnose conditions such as polycystic ovary syndrome, adrenal or ovarian androgen-secreting tumors, and androgen deficiency.
Who should get Free Androgen Index done in Gurugram?
PCOS is highly prevalent among Gurugram's young corporate women, driven by intense occupational stress, irregular sleep, sedentary work in Cyber City and DLF, and a high-refined-carbohydrate diet. Those who benefit most from Free Androgen Index testing include younger women with menstrual irregularities, couples planning conception, and anyone on hormone therapy. Timely testing in Gurugram shortens the path to an accurate diagnosis.
What conditions can Free Androgen Index help diagnose?
Abnormal results can come from obesity, insulin resistance, liver disease, thyroid problems, or certain medications, and family history of hormonal disorders may make testing more important.
What do Free Androgen Index results mean?
Higher or positive results: A high androgen index means your body has relatively elevated male hormones (androgens) compared with estrogens. Lower or negative results: Polycystic ovary syndrome is usually characterized by elevated androgens (hyperandrogenism), which cause symptoms like hirsutism, acne, and hair thinning. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.
How often should Free Androgen Index be repeated?
Frequency depends on the clinical question. For a fertility or PCOS work-up, tests are often timed to specific cycle days and repeated over one or two cycles. For patients on hormone therapy, monitoring follows the specialist's schedule, typically every few months until stable.
What happens after Free Androgen Index results are ready?
Results are delivered to your phone and stored securely on GetVisit. Any value the laboratory flags as critical is escalated for urgent review, and for everything else your doctor or a verified specialist can guide the next step at your convenience.
