What is a Free Androgen Index Test in Mumbai ?

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. In Mumbai, you can book this test online with home collection available in Malad, Kandivali, and beyond.

How is Free Androgen Index performed?

Collection is a routine blood draw. Using a single-use sterile needle, the phlebotomist takes a small sample from a vein in your arm; GetVisit's team in Malad and Kandivali, Mumbai then barcodes and transports it under controlled conditions to the NABL lab.

How accurate is Free Androgen Index?

Every GetVisit sample from Malad, Kandivali, and across Mumbai is processed at NABL-accredited labs that use internationally calibrated reference standards, pass external quality assessments, and maintain internal quality control at every shift. Reports are accepted by all major hospital networks, specialists, and insurance providers in India.

Are there any risks to Free Androgen Index?

This is a low-risk procedure whether done at a lab in Malad or by home collection in Kandivali, Mumbai. The only intervention is the blood draw. Side effects are limited to a brief pinch and an occasional small bruise that resolves in 24 to 48 hours. Patients on anticoagulants should hold light pressure for 3 to 5 minutes after the draw.

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).

Free Androgen Index Test Preparation in Mumbai

Managing medication:

For reproductive hormones (LH, FSH, oestradiol), collect on day 2 to 5 of your cycle unless told otherwise, and mention any hormonal contraceptive, which affects these values.

Fasting instructions:

You do not need to fast. Have your normal meals, but skip a heavy, oily meal and alcohol the evening before as a general precaution.

Timing:

Choose a morning slot for the most consistent results. Same-day home collection is offered throughout Mumbai, Thane and Vashi included.

What to bring along:

Bring your doctor's prescription, a valid photo ID, and your insurance card if you're using cashless OPD. Loose sleeves make collection easier.

Why Take a Free Androgen Index Test in Mumbai ?

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 Mumbai?

PCOS is increasingly diagnosed among Mumbai's young professional and corporate women. High occupational stress in the financial and media sectors concentrated in Lower Parel, Bandra-Kurla Complex, and Andheri West, combined with extremely long commute times disrupting sleep and meal patterns, creates the hormonal and metabolic disruption that drives PCOS in this population. Hormone testing benefits women with irregular cycles, suspected PCOS, or fertility concerns, and men with low energy, low libido, or reduced muscle mass. In Mumbai, high occupational stress and irregular sleep among professionals in Kandivali, Chembur, and similar areas are recognised contributors to hormonal imbalance.

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.

What is the normal range for free androgen index in PCOS?plus

The normal free androgen index (FAI) is generally considered below about 4–5% (FAI = total testosterone [nmol/L] ÷ SHBG [nmol/L] × 100). Values above approximately 4–5% suggest biochemical hyperandrogenism, often seen in PCOS. Reference ranges and cutoffs vary by lab and assay, so interpret results with clinical findings and local laboratory standards.

What does it mean when your androgen index is high?plus

A high androgen index means your body has relatively elevated male hormones (androgens) compared with estrogens. It often signals conditions such as polycystic ovary syndrome, adrenal or ovarian androgen-secreting tumors, or congenital adrenal hyperplasia. Symptoms include acne, excess facial/body hair, irregular periods, hair thinning, and fertility or metabolic issues. Doctors will evaluate with blood tests, imaging and targeted treatment to address the cause.

What is the free androgen index sample?plus

The free androgen index (FAI) is calculated from a blood (serum) sample measuring total testosterone and sex hormone–binding globulin (SHBG). A venous blood draw is usually done in the morning because testosterone levels vary through the day. The FAI estimates the proportion of biologically active (free) testosterone and helps assess androgen excess conditions such as polycystic ovary syndrome, hirsutism, or unexplained virilization.

How to calculate free androgen index FAI?plus

Calculate FAI by dividing total testosterone (in nmol/L) by SHBG (in nmol/L) and multiplying by 100: FAI = (total testosterone ÷ SHBG) × 100. If testosterone is reported in ng/dL, convert to nmol/L by multiplying by 0.0347 before calculating. FAI is expressed as a percentage; interpretive ranges vary, so review results with a clinician.

Can I take my diabetes medication before Free Androgen Index?plus

If you take insulin or diabetes tablets and are fasting for Free Androgen Index, ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.

Can Free Androgen Index be combined with a health package?plus

Yes. Free Androgen Index can be booked on its own or as part of a broader preventive health package on GetVisit, which often works out more cost-effective. You can choose either option before payment.
