Dehydroepiandrosterone (DHEA), Seven Specimens
Use
This test measures the level of Dehydroepiandrosterone (DHEA) in the blood. It is used to assess adrenal gland function and androgen production, which can help diagnose conditions such as adrenal insufficiency or hyperplasia, as well as certain cases of hirsutism and virilization. DHEA levels fluctuate throughout the day, so multiple specimens are tested to provide a comprehensive profile of hormone levels over time. This profile is crucial for evaluating how DHEA levels change in response to stimulation or suppression treatments administered during the test.
Special Instructions
This panel requires multiple specimen collections at different time intervals, following an initial baseline collection. After the initial tube is drawn, the patient is treated with a drug or other stimulus, and additional tubes are collected at several time points. It's essential to consult the Endocrine Appendix of the LabCorp Directory of Services for detailed instructions on multiple specimen collection and to confirm the necessity of this panel with the clinician before use.
Limitations
The test has not been cleared or approved by the FDA. The performance characteristics of this test have been determined by Labcorp. Interpreting the results requires correlating with clinical findings; inaccurate results may arise from improper handling of specimens or incorrect timing of specimen collection. Additionally, variations in testing schedules and reflex confirmation tests may alter the turnaround time.
