Dehydroepiandrosterone (DHEA) Sulfate, Eight Specimens
Use
This test measures the level of dehydroepiandrosterone sulfate (DHEA-S) in the blood across a series of samples. DHEA-S is a hormone produced by the adrenal glands. It's important in the development of male secondary sexual characteristics and can be converted into estrogen and testosterone. Monitoring DHEA-S levels can aid in the assessment of adrenal gland function and is often part of work-ups for hirsutism, amenorrhea, and as an indicator in evaluating prostate health, adrenal tumors, and certain forms of congenital adrenal hyperplasia.

Limitations
The results of this test can be influenced by the intake of biotin supplements. It is crucial to verify that the patient has stopped biotin supplementation at least 72 hours prior to sample collection to avoid interference. Additionally, variations in normal reference ranges may exist, and multiple specimens are tested to ensure accurate evaluation under elevated conditions and treatments.
