**Overview**: Androgen Index Panel**Introduction**: The Androgen Index Panel is a diagnostic tool designed to assess androgen status using serum samples. In India, hyperandrogenism is common in women with PCOS (affecting 20-30 percent in urban studies) and contributes to hirsutism, acne, menstrual irregularities, infertility, and metabolic syndrome. Free androgen index (FAI) calculation from total testosterone and SHBG is useful for evaluating androgen excess. High morbidity from underdiagnosis in rural/low-SES women, cultural stigma around hirsutism/infertility, limited endocrinology access, and delayed treatment leading to diabetes or cardiovascular risks. Per endocrinology and biochemistry practices aligned with ICMR and Indian Society of Endocrinology guidelines, the test employs immunoassay for parameter analysis over 1-2 days with high sensitivity/specificity, valuable for hormonal evaluation in hyperandrogenic states. This diagnostic falls under hormone screening and targets women with suspected androgen disorders, addressing accurate detection to guide anti-androgen therapy or lifestyle interventions. With elevated morbidity due to underdiagnosis, the test supports public health efforts by enabling precise identification, facilitating management, and reducing long-term metabolic complications. Its serum-based approach ensures reliable performance in India's diverse lab settings.**Other Names**: Androgen Pnl.**FDA Status**: FDA approved, CLIA certified for endocrinology/biochemistry, compliant with 2025 standards.**Historical Milestone**: Developed with FAI calculation; in India, prominence with PCOS epidemic.**Purpose**: The test assesses 3 parameters including total testosterone and SHBG to calculate free androgen index, evaluate androgen status, inform treatment in hyperandrogenic disorders.**Test Parameters**: 1. Total Testosterone, 2. SHBG, 3. Free Androgen Index.**Pretest Condition**: Fasting 10-12 hours recommended; patients should report hirsutism, acne, menstrual irregularities, or infertility.**Specimen**: 3 mL serum in 1 SST, transported within specified times to maintain sample viability.**Sample Stability at Room Temperature**: 8 hours with proper handling to preserve analyte integrity, ensuring reliable test performance.**Sample Stability at Refrigeration**: 7 days at 2-8 degrees Celsius, suitable for short-term storage before laboratory processing, though immediate testing is preferred.**Sample Stability at Frozen**: 6 months at -20 degrees Celsius, allowing long-term storage for retesting, though freezing may affect some analytes.**Medical History**: Patients should provide details on menstrual history, hirsutism, acne, weight gain, infertility, family history of PCOS or endocrine disorders.**Consent**: Written informed consent is required, detailing the test's purpose, potential risks of untreated hyperandrogenism including infertility or metabolic syndrome, benefits of early detection, and minimal discomfort from venipuncture.**Procedural Considerations**: The test involves sample processing using immunoassay by trained personnel to ensure sterile technique, avoid hemolysis, and interpret results within 1-2 days using provided controls. Laboratories must maintain a controlled environment, adhere to quality assurance protocols, and store kits according to manufacturer specifications to ensure reliability.**Factors Affecting Result Accuracy**: Delays beyond stability periods, improper storage conditions, hemolysis, or recent medications can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.**Clinical Significance**: Abnormal results indicate hyperandrogenism, necessitating further investigation like specialist consultation or additional testing. Normal results may require follow-up if symptoms persist.**Specialist Consultation**: Endocrinologists or gynecologists should be consulted for case management, treatment planning, and coordination with women's health programs.**Additional Supporting Tests**: Pelvic ultrasound, insulin levels, or lipid profile for confirmation.**Test Limitations**: The test may miss non-androgen causes or require cycle timing; comprehensive approach with clinical correlation required.**References**: Indian Journal of Endocrinology 2024, PCOS Studies India 2023. |
