What is this test?
DHEA-S is an androgen hormone produced mainly by the adrenal glands and serves as a source for other sex hormones.
Why might it be ordered?
- For signs of increased androgens, such as abnormal hair growth, acne or menstrual irregularities.
- To assess whether the source of androgen bias may be the adrenal gland.
What sample is needed?
A healthcare professional collects a venous blood sample. Depending on the method, the laboratory uses serum or plasma.
How should you prepare?
Tell the laboratory about all medicines, hormone treatments, vitamins and supplements you take. Do not stop or change treatment unless your clinician tells you to. Follow any instructions about fasting and the time of collection.
How should you understand the result?
The result depends strongly on age and sex and is interpreted with testosterone, androstenedione and other hormones. Your result is interpreted using the reference interval on the laboratory report and in the context of your symptoms, medical history and other test findings.
