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).

Free Androgen Index Test Preparation in Gurugram

Fasting instructions:

There is no need to skip food or drink for this test. Staying well hydrated beforehand simply makes the sample easier to collect.

What to bring along:

Keep your prescription and ID handy, along with your OPD insurance details if applicable. Wear sleeves that roll up easily.

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.

Timing:

Morning appointments suit most tests, when the body's markers are most stable. GetVisit home collection in Gurugram starts at 6:00 AM, including New Colony and Cyber City.

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.

Frequently asked questions

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 menstruation affect Free Androgen Index results?plus

Some tests, such as iron studies and certain hormone panels, can be influenced by your menstrual cycle. If you are on your period, mention it so your doctor can judge whether timing matters for Free Androgen Index.

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.
