Preparing for a Dehydroepiandrosterone (DHEA) Blood Test in Bellwood, IL starts with three questions: whether you need to fast, when to collect, and what to bring. This blood test measures levels of dehydroepiandrosterone (DHEA), a hormone produced by the adrenal glands.
What the Dehydroepiandrosterone (DHEA) Blood Test measures
The test measures the concentration of DHEA in the blood. Because DHEA is produced primarily by the adrenal glands, its level can provide information about adrenal activity. Results are typically interpreted alongside other clinical findings and hormone tests.
- Dehydroepiandrosterone (DHEA)
- Adrenal function
- Hormone balance

Fasting, timing, sample type, and what to bring
Fasting
Some labs may ask you to fast for a certain number of hours before this test, while others do not require fasting. Confirm with your lab whether fasting is needed for your specific test.
Best time to collect
DHEA levels can vary throughout the day, so your clinician may recommend a specific collection time, often in the morning. Follow the timing instructions provided by your testing location.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- Your order confirmation email, in case the collection site asks to see it
- A written list of the medications and supplements you currently take
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
At the collection site
A healthcare professional will clean an area on your arm and insert a needle into a vein to collect a small sample of blood. The sample is then sent to a laboratory for analysis, and the procedure usually takes only a few minutes.
Details worth confirming with the collection lab before your visit:
- Do I need to fast before this test?
- Is there a specific time of day I should have my blood drawn?
- Should I take my medications or supplements as usual before the test?
Why the Dehydroepiandrosterone (DHEA) Blood Test may be ordered

Reading your results responsibly
Reference ranges for DHEA can vary between laboratories and may depend on factors such as age and sex. Your results should be interpreted by your healthcare provider using the range provided by the testing lab.
