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.
