Overview: Dehydroepiandrosterone (DHEA) TestIntroduction: The Dehydroepiandrosterone (DHEA) Test measures DHEA to assess adrenal or hormonal disorders, causing fatigue or infertility. Aligned with 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 hormonal imbalances.
Other Names: DHEA Assay, Adrenal Hormone Test.
FDA Status: Laboratory-developed test (LDT), meeting endocrinology standards for diagnostic accuracy.
Historical Milestone: DHEA 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 levels in patients with fatigue or infertility.
Test Parameters: 1. Dehydroepiandrosterone
Pretest Condition: Fasting for 10-12 hours required to stabilize hormone levels. Collect serum, plasma, or saliva in the morning. Report symptoms like fatigue or infertility, and list medications.
Specimen: 2-5 mL serum (SST), 2-4 mL plasma (EDTA), or 1-2 mL saliva (sterile container). Centrifuge serum/plasma 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, infertility, 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 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 levels suggest adrenal disorders (e.g., adrenal insufficiency), prompting treatment. Normal levels may require further testing.
Specialist Consultation: Consult an endocrinologist or reproductive specialist for result interpretation.
Additional Supporting Tests: DHEA-S, cortisol levels, or adrenal imaging to confirm adrenal disorders.
Test Limitations: Results may be affected by stress or medications. Clinical correlation is required.
