Dehydroepiandrosterone (DHEA), Three Specimens
Use
The Dehydroepiandrosterone (DHEA) test involves collecting and measuring DHEA levels across three time points. It is used to evaluate adrenal function and determine any abnormal production of DHEA. This test can assist in diagnosing conditions such as adrenal tumors or hyperplasia and in monitoring DHEA supplementation.
Special Instructions
This panel requires multiple tubes to be drawn at different time points. An initial sample is collected, followed by treatment (such as a pill or shot), then further samples. Ensure coordination with the clinician to confirm the need for this series and the specific treatment process involved.
Limitations
The DHEA test results can be influenced by factors such as sample handling, patient preparation, and timing of sample collection. It is critical to adhere to the prescribed collection protocol to ensure accurate results. Additionally, the test does not identify specific causes of altered DHEA levels, which require further investigation.
