DHEA (Dehydroepiandrosterone), Unconjugated
It measures unconjugated DHEA to assess adrenal androgen production and hormone balance, with easy ordering and Quest-based labs through Vitals Vault.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.
This test measures unconjugated DHEA (dehydroepiandrosterone), a hormone your adrenal glands make and your body can convert into other androgens and estrogens.
Because DHEA sits “upstream” in hormone pathways, your result can help explain patterns like androgen-related skin or hair changes, shifts in libido, or unclear fatigue when other labs look normal.
DHEA results are easiest to interpret when you consider your age, sex, symptoms, and any hormone medications or supplements you use. A single number rarely tells the whole story, but it can point you toward the next most useful tests and follow-up steps.
Do I need a DHEA (Unconjugated) test?
You may want a DHEA (unconjugated) test if you are trying to understand possible adrenal androgen patterns. People often check it when they have acne or oily skin that started or worsened in adulthood, increased facial or body hair, scalp hair thinning, or irregular cycles that raise the question of androgen excess.
This test can also be useful if you have low libido, low energy, or reduced stress tolerance and you are looking for a hormone-based explanation. DHEA naturally changes with age, so the “right” interpretation depends on whether your value fits your life stage and clinical picture.
You may also need this test if you are already using DHEA supplements or certain hormone therapies and want to confirm you are not overshooting. Testing supports clinician-directed care and shared decision-making; it is not a stand-alone way to diagnose a condition on your own.
This is a laboratory-developed test performed in a CLIA-certified lab; results should be interpreted alongside symptoms and related hormone markers rather than used as a diagnosis by themselves.

Key benefits of DHEA (Unconjugated) testing
- Checks adrenal androgen production when symptoms suggest hormone imbalance.
- Helps distinguish “upstream” androgen patterns from downstream markers like testosterone alone.
- Adds context for acne, hirsutism, or scalp hair thinning when the cause is unclear.
- Supports safer use of DHEA supplements by showing whether your dose is pushing levels high.
- Provides a baseline before starting or adjusting hormone-related therapies.
- Guides smart follow-up testing (for example, DHEA-S, testosterone, SHBG, and 17-hydroxyprogesterone).
- Makes it easier to monitor trends over time with consistent lab ordering and PocketMD guidance.
What is DHEA (Unconjugated)?
DHEA (dehydroepiandrosterone) is a steroid hormone made primarily by your adrenal glands, with smaller contributions from the ovaries or testes. “Unconjugated” DHEA refers to the circulating form that has not been sulfated (converted into DHEA-S, dehydroepiandrosterone sulfate).
DHEA is a precursor hormone, meaning your body can convert it into other hormones depending on your tissues and enzyme activity. It can be converted into androgens (like testosterone and dihydrotestosterone) and, through additional steps, into estrogens. Because of that, DHEA can be a useful piece of the puzzle when you are evaluating androgen-related symptoms.
DHEA and DHEA-S are related but not identical. DHEA-S is usually more stable throughout the day and is often used as a longer-term marker of adrenal androgen production, while unconjugated DHEA may fluctuate more and can be more sensitive to recent supplementation. Your clinician may choose one or both depending on the question you are trying to answer.
Why your adrenal glands matter
Your adrenal glands respond to signals from your brain (ACTH, adrenocorticotropic hormone) and produce several hormones, including cortisol and adrenal androgens. When adrenal androgen output is higher or lower than expected for your age and sex, you may notice changes in skin, hair, mood, libido, or cycle regularity.
Unconjugated DHEA vs. DHEA-S
DHEA-S is the sulfated storage/transport form and tends to have less short-term variability. Unconjugated DHEA can change more with timing, acute stress, and especially with DHEA supplements, which is why it can be helpful when you are assessing dosing or recent changes.
What do my DHEA (Unconjugated) results mean?
Low DHEA (unconjugated) levels
A low result can mean your adrenal androgen production is lower than expected for your age, or that your body is preferentially converting DHEA into other pathways. Some people with low DHEA report low libido, reduced sense of well-being, or low energy, but symptoms are not specific and can overlap with thyroid issues, anemia, sleep problems, depression, or under-fueling. If your result is low, it is often helpful to review DHEA-S, cortisol patterns (if clinically indicated), thyroid labs, and sex hormones to see whether the finding fits a broader pattern.
Optimal (in-range) DHEA (unconjugated) levels
An in-range result generally suggests your adrenal androgen output is consistent with the lab’s reference interval for your age and sex. If you still have symptoms, an “in-range” DHEA does not rule out hormone-related causes, because conversion to downstream hormones can vary between people. In that situation, pairing your result with testosterone (total and/or free), SHBG (sex hormone–binding globulin), and sometimes DHEA-S can clarify whether the issue is production, binding, or conversion.
High DHEA (unconjugated) levels
A high result can reflect increased adrenal androgen production, recent DHEA supplementation, or less commonly an adrenal source that needs medical evaluation. In many real-world cases, supplements are the most common reason for unexpectedly high unconjugated DHEA, especially if the dose changed recently. If your level is high and you have acne, unwanted hair growth, scalp hair thinning, or cycle changes, your clinician may consider follow-up testing (often including DHEA-S, testosterone, and 17-hydroxyprogesterone) to narrow down the cause and decide whether imaging or specialty care is appropriate.
Factors that influence DHEA (unconjugated)
Age is a major driver, because DHEA tends to peak in early adulthood and decline over time, so interpretation should be age-aware. Time of day, acute stress, and recent illness can shift adrenal hormone output and add noise to a single measurement. Medications and hormones (including oral contraceptives, glucocorticoids, and some fertility or gender-affirming regimens) can affect androgen pathways. DHEA supplements can raise unconjugated DHEA quickly, so you should tell your clinician exactly what you take and when you last took it before the blood draw.

Frequently Asked Questions
What is the difference between DHEA and DHEA-S?
They are related forms of the same hormone family. DHEA-S (sulfate) is a more stable storage/transport form and often reflects longer-term adrenal androgen output, while unconjugated DHEA can fluctuate more and may respond quickly to DHEA supplementation.
Do I need to fast for a DHEA (unconjugated) blood test?
Fasting is not typically required for DHEA testing, but your clinician or the lab order may bundle it with other tests that do require fasting. If you are also checking glucose, insulin, or lipids, follow the fasting instructions for the full panel.
When is the best time of day to test DHEA?
Many clinicians prefer a morning blood draw for adrenal-related hormones to reduce variability and make results easier to compare over time. If you are trending results, try to test at a similar time of day each time.
Should I stop taking DHEA supplements before testing?
If the goal is to measure your baseline production, your clinician may recommend stopping DHEA for a period before the draw. If the goal is to monitor your current dose, you may be told to continue and document the dose and timing. Do not change prescription medications without medical guidance.
What can cause high DHEA in women?
Common causes include DHEA supplementation and increased adrenal androgen production. Depending on your symptoms and other hormone results, your clinician may evaluate for conditions associated with androgen excess and may add tests like DHEA-S, testosterone, SHBG, and 17-hydroxyprogesterone.
What can cause low DHEA?
DHEA tends to decline with age, and levels can also be lower with certain medications (for example, glucocorticoids) or chronic illness and undernutrition. Because symptoms are nonspecific, low DHEA is usually interpreted alongside thyroid markers, iron status, sex hormones, and your overall clinical context.
How often should I retest DHEA (unconjugated)?
If you are monitoring a change (such as starting or adjusting a supplement or hormone plan), retesting is often done after several weeks to a few months, depending on the intervention and your clinician’s goals. If you are stable and asymptomatic, repeat testing may not be necessary unless something changes.
