DHEA-S Blood Test: Meaning, Levels, and Interpretation
The dhea s blood test measures dehydroepiandrosterone sulfate levels to assess adrenal gland function. Normal ranges depend on age and sex but typically decline with age. High levels may indicate adrenal overactivity or conditions like PCOS, while low levels suggest adrenal insufficiency or aging. This dhea sulfate lab test helps identify the source of hormone imbalance.

Result interpretation DHEA-S
What your result means based on common reference ranges
DHEA-S levels within range reflect normal adrenal function and balanced androgen production without endocrine disorder signs.
Mildly elevated DHEA-S levels often suggest adrenal overactivity linked to PCOS or chronic stress conditions.
Significantly high DHEA-S levels may indicate adrenal tumors or hyperplasia requiring urgent endocrine evaluation.
Low DHEA-S levels suggest adrenal insufficiency, aging-related decline, or impaired pituitary signaling affecting hormone production.

What is DHEA-S?
The DHEA-S blood test evaluates the level of a stable androgen produced mainly by the adrenal glands. As a precursor hormone, DHEA-S contributes to the production of testosterone and estrogen, making it important in endocrine balance. Unlike other hormones, its level does not fluctuate significantly during the day, improving test reliability. Clinically, it helps differentiate adrenal disorders from ovarian or testicular causes of androgen excess. Abnormal DHEA-S levels are often linked to conditions such as PCOS, adrenal tumors, or adrenal insufficiency, and are commonly assessed alongside cortisol and testosterone in hormonal evaluation.
Reference ranges
Causes of abnormal values
Causes of low DHEA-S
- • Aging — natural decline in adrenal androgen production over time
- • Adrenal insufficiency — damaged glands reduce hormone synthesis
- • Hypopituitarism — reduced ACTH lowers adrenal stimulation
- • Glucocorticoid therapy — steroid use suppresses endogenous hormone production
Causes of high DHEA-S
- • PCOS — excess androgen production from ovarian and adrenal sources
- • Adrenal hyperplasia — congenital enlargement increases hormone synthesis
- • Adrenal tumors — autonomous hormone secretion from benign or malignant growths
- • Cushing's disease — pituitary overstimulation increases adrenal hormone output
- • Chronic stress — prolonged activation of adrenal glands raises androgen levels
- • Early puberty — premature adrenal activation increases DHEA-S production
DHEA-S in combination with other markers
Possible symptoms
- •Excess facial or body hair (hirsutism)
- •Acne and oily skin
- •Irregular menstrual cycles
- •Hair thinning on scalp
- •Weight gain around abdomen
When to see a doctor
Consult a doctor if DHEA-S levels exceed 700 mcg/dL in women or 800 mcg/dL in men. Seek evaluation if symptoms like rapid virilization, infertility, or persistent hormonal imbalance occur. Repeated abnormal results or worsening trends also require medical assessment.
What to do if abnormal
- Repeat test to confirm abnormal levels
- Consult endocrinologist for hormonal evaluation
- Perform imaging if levels are significantly elevated
- Review medications affecting hormone levels
- Improve sleep and stress management
