High DHEA sulfate (DHEA-S) means your adrenal glands are producing more of this hormone than expected for your age and sex. DHEA-S is a precursor hormone, meaning your body converts it into other hormones, including testosterone and estrogen. Because of this, elevated levels can cause symptoms related to excess androgens (male-type hormones), particularly in women. In some cases, a high reading is harmless, but levels at or above 600 mcg/dL raise concern for an adrenal tumor and typically prompt imaging.
What DHEA-S Does in Your Body
DHEA-S is produced almost entirely by the adrenal glands, the small organs that sit on top of your kidneys. It circulates in your blood at higher concentrations than nearly any other hormone, serving as raw material your body draws on to make testosterone, estrogen, and other sex hormones. On its own, DHEA-S is relatively inactive. Its effects come from what it gets converted into downstream.
DHEA-S levels follow a predictable arc over a lifetime. They spike briefly in newborns, drop during childhood, then rise sharply during puberty. Levels peak in your late twenties and decline steadily after that. This natural decline is why the normal range shifts so dramatically with age: a reading of 400 mcg/dL would be perfectly normal for a 25-year-old man but notably high for a 60-year-old.
Normal Ranges by Age and Sex
DHEA-S is measured in micrograms per deciliter (mcg/dL). The ranges below, based on Mayo Clinic laboratory values, show how much the expected range narrows as you get older.
Males
- 18 to 30 years: 105 to 728 mcg/dL
- 31 to 40 years: 57 to 522 mcg/dL
- 41 to 50 years: 34 to 395 mcg/dL
- 51 to 60 years: 20 to 299 mcg/dL
- 61 to 70 years: 12 to 227 mcg/dL
- 71+ years: 6.6 to 162 mcg/dL
Females
- 18 to 30 years: 83 to 377 mcg/dL
- 31 to 40 years: 45 to 295 mcg/dL
- 41 to 50 years: 27 to 240 mcg/dL
- 51 to 60 years: 16 to 195 mcg/dL
- 61 to 70 years: 9.7 to 159 mcg/dL
- 71+ years: 5.3 to 124 mcg/dL
A result above the upper end of your age-specific range is what your doctor means by “high.” Because the ranges are so broad, context matters. A mildly elevated result in a young adult is interpreted very differently from the same number in a postmenopausal woman.
Symptoms of High DHEA-S
The effects of elevated DHEA-S depend largely on sex. Because the excess hormone gets converted into androgens, women and girls tend to notice symptoms first and most clearly. These can include excess body and facial hair growth, acne (often deep and persistent), thinning hair at the top of the head, irregular or absent periods, voice deepening, increased muscle bulk, and difficulty getting pregnant.
Adult men with high DHEA-S often have no obvious symptoms at all, since their bodies already operate in a higher-androgen environment. The exception is boys who haven’t reached puberty yet. In them, elevated DHEA-S can trigger early puberty, with body hair, growth spurts, and other changes appearing years ahead of schedule.
Common Causes
Several conditions can push DHEA-S above normal. The cause your doctor investigates first depends on how high the level is, your age, and what other symptoms you have.
Polycystic ovary syndrome (PCOS) is one of the most common reasons women get tested. About 20 to 30 percent of women with PCOS have mildly to moderately elevated DHEA-S alongside irregular periods and signs of excess androgens. DHEA-S alone doesn’t diagnose PCOS, but it helps distinguish whether the excess androgens are coming from the adrenal glands, the ovaries, or both.
Non-classic congenital adrenal hyperplasia (NCAH) is a genetic condition where an enzyme needed for cortisol production doesn’t work efficiently. The adrenal glands compensate by overproducing other hormones, including DHEA-S. NCAH can look nearly identical to PCOS on blood work. The key differentiator is a separate hormone called 17-hydroxyprogesterone, which runs significantly higher in NCAH. Genetic testing for a specific gene variant (CYP21A2) can confirm the diagnosis when blood work is ambiguous.
Cushing syndrome, caused by chronic cortisol excess, can also raise DHEA-S. Stress on the adrenal glands from any cause, including prolonged physical or emotional stress, can contribute to modest elevations as well.
Adrenal tumors are a less common but more serious possibility, discussed in detail below.
When High Levels Signal Something Serious
Mild elevations in adults are usually benign or linked to manageable conditions like PCOS. The threshold that raises concern is around 600 mcg/dL. According to Mayo Clinic Laboratories, levels at or above 600 mcg/dL can suggest an androgen-secreting adrenal tumor. More than 90% of patients with such tumors have DHEA-S levels well above this cutoff.
If your result crosses this line, your doctor will likely order imaging of the adrenal glands, typically a CT scan, to look for a mass. Not all adrenal tumors are cancerous. Many are benign adenomas that can be surgically removed. But the high DHEA-S level itself is what flags the need to look, which is why this number matters.
How the Test Works
DHEA-S is measured with a simple blood draw. One practical advantage of this test is that DHEA-S levels remain relatively stable throughout the day and don’t fluctuate significantly with the menstrual cycle, so there’s no special timing required. You generally don’t need to fast, though your lab may have its own instructions.
One thing worth knowing: DHEA is sold as an over-the-counter supplement. If you’re taking a DHEA supplement, it will raise your DHEA-S levels on a blood test, which can make results misleading. Be sure to mention any supplements to your provider before the test.
What Happens After an Elevated Result
A single high DHEA-S result is a starting point, not a diagnosis. Your doctor will typically look at other hormone levels alongside it, including testosterone, cortisol, and 17-hydroxyprogesterone, to narrow down the source. The combination of results, along with your symptoms and medical history, guides the next steps.
Treatment targets the underlying cause rather than the DHEA-S number itself. For PCOS, this might mean hormonal birth control to regulate periods and reduce androgen effects, or medications that block androgen activity to address acne and unwanted hair growth. For NCAH, low-dose glucocorticoids can reduce adrenal overproduction. For adrenal tumors, surgery is the primary approach. In cases where a mild elevation has no clear cause and no symptoms, monitoring over time without treatment is common.
