Overview: Dehydroepiandrosterone-Sulfate (DHEA-S) TestIntroduction: The Dehydroepiandrosterone-Sulfate (DHEA-S) Test measures DHEA sulphate to assess adrenal function, linked to hormonal imbalances causing fatigue or hair loss. Following 2023 Endocrine Society guidelines, it uses an immunoassay for high sensitivity, aiding in endocrine screening. This test is critical for guiding diagnosis, treatment, and improving outcomes in endocrinology for patients with suspected adrenal disorders.
Other Names: DHEA Sulphate Assay, Adrenal Hormone Test.
FDA Status: Laboratory-developed test (LDT), meeting endocrinology standards for diagnostic accuracy.
Historical Milestone: DHEA-S testing began in the 1970s with adrenal research. Immunoassays emerged in the 1980s, and by the 2000s, high-sensitivity assays improved accuracy.
Purpose: Diagnoses adrenal or hormonal disorders, guides treatment, and monitors DHEA-S levels in patients with fatigue or hair loss.
Test Parameters: 1. Dehydroepiandrosterone Sulphate
Pretest Condition: Fasting for 10-12 hours required to stabilize hormone levels. Collect serum or plasma in the morning. Report symptoms like fatigue or hair loss, and list medications.
Specimen: 2-5 mL serum (SST) or 2-4 mL plasma (EDTA). Centrifuge within 1 hour. Transport in a biohazard bag within 8 hours.
Sample Stability at Room Temperature: 8 hours
Sample Stability at Refrigeration: 7 days
Sample Stability at Frozen: 6 months
Medical History: Document fatigue, hair loss, or history of adrenal/hormonal disorders. Include current medications, especially steroids.
Consent: Written consent required, detailing the tests purpose, diagnostic implications, and potential need for hormonal therapy.
Procedural Considerations: Uses an immunoassay to measure DHEA-S levels. Results are available in 1-2 days, enabling rapid clinical decisions.
Factors Affecting Result Accuracy: Non-fasting, stress, or medications can affect results. Hemolysis may degrade samples.
Clinical Significance: Abnormal DHEA-S levels suggest adrenal disorders (e.g., PCOS, adrenal hyperplasia), prompting treatment. Normal levels may require further testing.
Specialist Consultation: Consult an endocrinologist for result interpretation.
Additional Supporting Tests: Cortisol levels, ACTH stimulation test, or adrenal imaging to confirm adrenal disorders.
Test Limitations: Results may be affected by stress or medications. Clinical correlation is required.
