What is a Free Androgen Index Test in Bengaluru ?

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. If you have these symptoms, GetVisit offers booking and home collection across Sarjapur Road, Hebbal, and other parts of Bengaluru.

How is Free Androgen Index performed?

You can have the sample for Free Androgen Index taken at home in Sarjapur Road or Hebbal, Bengaluru, or at a partner lab. The phlebotomist draws a small amount of blood, applies a cotton swab with light pressure, and dispatches the sample to the NABL-accredited lab the same day.

How accurate is Free Androgen Index?

Every GetVisit sample from Sarjapur Road, Hebbal, and across Bengaluru 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?

A blood draw for Free Androgen Index is very safe. Occasionally there is minor bruising or light-headedness; sitting for a couple of minutes afterwards at the Sarjapur Road or Hebbal, Bengaluru collection point usually prevents this.

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 Bengaluru

Diet and fasting:

No special diet or fasting is needed. Carry on normally; just stay hydrated and avoid alcohol the night before.

What to carry:

Have your doctor's referral and photo ID ready; earlier reports for the same test are useful for tracking trends.

Medication guidance:

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.

When to book:

Book whenever is convenient; for fasting or hormone tests an early-morning slot is ideal. GetVisit covers JP Nagar, Rajajinagar, and all of Bengaluru.

Why Take a Free Androgen Index Test in Bengaluru ?

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 Bengaluru?

PCOS prevalence among Bengaluru's young IT sector women is reported well above national averages. 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 Bengaluru 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?

Reports arrive digitally and remain in your GetVisit history, so repeat tests can be tracked over months and years. Review anything unexpected with your doctor before changing medication or lifestyle, and use the app to book a follow-up if needed.

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.
