Overview: Steroid 1 Panel
Introduction: The Steroid 1 Panel is a diagnostic tool designed to screen for steroid hormone levels using serum samples. In India, disorders of steroidogenesis (CAH, PCOS, adrenal insufficiency) affect reproductive and metabolic health, with CAH prevalence ~1 in 10,000-15,000 births and PCOS ~20-30 percent in women. High morbidity from under-testing in rural/low-SES patients with infertility, hirsutism, or adrenal crisis, limited endocrine labs, delayed glucocorticoid/mineralocorticoid replacement or anti-androgen therapy leading to complications. Per endocrinology practices aligned with ICMR and Endocrine Society of India guidelines, the test employs spectrophotometry for cortisol, testosterone, DHEAS, androstenedione, 17-OHP, and estradiol over 1-2 days with high accuracy, valuable for adrenal/reproductive axis evaluation. This diagnostic falls under endocrine screening and targets patients with hirsutism, infertility, or adrenal symptoms, addressing accurate detection to guide hormone replacement or suppression. With elevated morbidity due to underdiagnosis, the test supports public health efforts by enabling precise steroid profiling and reducing endocrine disorder burden. Its serum-based approach ensures reliable multi-hormone assessment.
Other Names: Steroid 1 Pnl.
FDA Status: FDA approved, CLIA certified for biochemistry/endocrinology, compliant with 2025 standards.
Historical Milestone: Steroid hormone panels standard in endocrinology; in India, used in reproductive clinics.
Purpose: The test assesses 6 parameters including cortisol to guide hormonal disorder screening, detect imbalances, inform replacement/suppression.
Test Parameters: 1. Cortisol, 2. Testosterone, 3. DHEAS, 4. Androstenedione, 5. 17-OHP, 6. Estradiol.
Pretest Condition: Fasting 10-12 hours recommended; patients should have endocrine symptoms.
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 hirsutism, infertility, fatigue.
Consent: Written informed consent is required, detailing the test's purpose, potential risks of undetected imbalance including infertility, benefits of screening, and minimal discomfort from venipuncture.
Procedural Considerations: The test involves sample processing using spectrophotometry 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.
Factors Affecting Result Accuracy: Delays beyond stability periods, improper storage conditions, hemolysis can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.
Clinical Significance: Abnormal levels indicate CAH, PCOS, or adrenal issues, necessitating specialist input.
Specialist Consultation: Endocrinologists should be consulted for management.
Additional Supporting Tests: ACTH stimulation, pelvic ultrasound for confirmation.
Test Limitations: Time-of-day dependent; comprehensive approach required.
