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.
Special Instructions
This panel requires the collection of multiple tubes at different time points. An initial baseline tube is collected, followed by further samples after administering a drug or treatment. Do not use this panel unless the patient is receiving treatment after the first sample. It is important to check for biotin intake, as it may interfere with results. Patients should stop consuming biotin 72 hours before the test.
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.
