Overview: Steroid 3 Panel
Introduction: The Steroid 3 Panel is a diagnostic tool designed for comprehensive steroid profiling using serum samples. In India, full steroid panel evaluation is crucial for complex endocrine disorders (CAH variants, adrenal tumors, PCOS, hypogonadism), assessing mineralocorticoids (aldosterone), androgens (DHT), estrogens (estriol), and binding proteins (SHBG). High morbidity from under-testing in rural/low-SES patients with ambiguous genitalia, infertility, or adrenal crisis, limited advanced endocrine labs, delayed targeted therapy leading to complications. Per endocrinology practices aligned with ICMR and Endocrine Society of India guidelines, the test employs spectrophotometry for 13 steroid hormones and related markers over 1-2 days with high accuracy, valuable for detailed adrenal/gonadal axis assessment. This diagnostic falls under endocrine screening and targets patients with complex hormonal symptoms or ambiguous genitalia, addressing accurate detection to guide specific replacement or suppression. With elevated morbidity due to underdiagnosis, the test supports public health efforts by enabling advanced steroid profiling and reducing diagnostic delay. Its serum-based approach ensures reliable multi-steroid evaluation.
Other Names: Steroid 3 Pnl.
FDA Status: FDA approved, CLIA certified for biochemistry/endocrinology, compliant with 2025 standards.
Historical Milestone: Comprehensive steroid profiling standard in tertiary endocrinology; in India, used in specialized centers.
Purpose: The test assesses 13 parameters including cortisol to guide comprehensive hormonal disorder screening, detect imbalances, inform therapy.
Test Parameters: 1. Cortisol, 2. Testosterone, 3. DHEAS, 4. Androstenedione, 5. 17-OHP, 6. Estradiol, 7. Progesterone, 8. Aldosterone, 9. DHEA, 10. 11-Deoxycortisol, 11. Estriol, 12. DHT, 13. SHBG.
Pretest Condition: Fasting 10-12 hours recommended; patients should have complex 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 virilization, infertility, adrenal symptoms.
Consent: Written informed consent is required, detailing the test's purpose, potential risks of undetected disorder including complications, 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 multi-steroid pattern indicates CAH, tumor, or PCOS, necessitating specialist input.
Specialist Consultation: Endocrinologists should be consulted for management.
Additional Supporting Tests: ACTH stimulation, imaging for confirmation.
Test Limitations: Requires clinical correlation; comprehensive approach required.
