Have you ever noticed unexplained changes in your body such as increased body hair, acne, or persistent fatigue? Or are you wondering about the causes of irregular menstrual cycles or puberty-related disorders in children? In many cases, the answer lies in Dehydroepiandrosterone (DHEA), a hormone produced by the adrenal glands that plays a crucial role in the production of sex hormones such as testosterone and estrogen.In this Dalily Medical article, we provide a complete guide to the DHEA blood test, including the reasons for performing the test, how it is done, normal reference values, causes of high or low levels, and how to accurately interpret the results. We also highlight important medical advice for individuals who may be at higher risk of hormonal imbalances.Whether you are seeking reliable medical information or trying to better understand your hormonal health, this comprehensive guide will help you fully understand the DHEA test and its importance.
The DHEA test measures the level of Dehydroepiandrosterone in the blood. DHEA is a hormone produced mainly by the adrenal glands and plays an important role in the production of sex hormones such as testosterone and estrogen.
Total DHEA: Measures the total amount of DHEA circulating in the blood.
DHEA-S (Dehydroepiandrosterone Sulfate): The sulfated form of DHEA, which is more stable in the bloodstream and provides a more accurate assessment of adrenal gland function.
Symptoms of excess androgens such as excessive hair growth, acne, or irregular menstrual cycles in women
Evaluation of early or delayed puberty in children and adolescents
Assessment of adrenal gland function
Monitoring conditions such as Polycystic Ovary Syndrome (PCOS) or other adrenal disorders
Fasting is not usually required
The test is preferably performed in the morning, as DHEA-S levels are naturally higher and results are more accurate
The test is safe and simple, requiring only a venous blood sample
You may feel a brief needle prick or develop a small bruise, which usually resolves quickly
(Values may vary slightly depending on the laboratory)
Men: 80–560 µg/dL
Women: 35–430 µg/dL
Children: 10–50 µg/dL
✔️ Yes, it is completely safe during pregnancy since it involves only a blood sample.
It may be requested when hormonal imbalance is suspected.
The need for repeat testing depends on the clinical condition, such as:
Monitoring hormonal therapy
Follow-up of adrenal gland disorders
Monitoring PCOS
To evaluate adrenal gland activity
To investigate causes of excessive hair growth, acne, or menstrual irregularities
To assess puberty disorders in children and adolescents
A venous blood sample is collected
No fasting is required, but morning testing is recommended
Most laboratories provide accurate results
Some medications or supplements may affect DHEA-S levels
Repeat testing may be required to confirm abnormal results
Adrenal gland overactivity or adrenal tumors
Polycystic Ovary Syndrome (PCOS)
Use of hormonal supplements or chronic stress
Adrenal insufficiency
Normal aging
Effects of medications such as corticosteroids or immunosuppressants
High levels: Excessive hair growth, acne, menstrual irregularities, possible weight gain
Low levels: Fatigue, muscle weakness, low libido, reduced stress tolerance
Yes. DHEA-S levels vary with:
Age
Menstrual cycle
Stress levels
Chronic illnesses
✔️ Yes. It is safe for children, adults, and pregnant women.
Extremely high or low results
Persistent symptoms such as excessive hair growth, menstrual problems, or severe fatigue
Measures total circulating DHEA
Used to assess general hormone production and adrenal function
Measures the stable sulfated form
Helps determine whether androgen excess originates from the adrenal glands or ovaries
Used in diagnosing adrenal disorders and PCOS
Measures biologically active free DHEA
Used mainly in specialized or research settings
High levels: PCOS, hirsutism, acne
Low levels: Long-term corticosteroid use
High levels: Early puberty or adrenal hyperactivity
Low levels: Delayed puberty or adrenal insufficiency
Natural decline with age
Excessive decline may cause fatigue, muscle loss, and low libido
Adrenal tumors
Adrenal insufficiency
Corticosteroids, immunosuppressants, chemotherapy drugs, or hormonal supplements
Abnormal levels may affect hormonal balance
Testing is done when clinically indicated
Evaluation of adrenal gland disorders
Diagnosis of androgen excess
Assessment of infertility causes
Diagnosis and monitoring of PCOS
Monitoring hormonal treatments
Investigation of chronic fatigue and mood changes
The DHEA-S test measures the level of Dehydroepiandrosterone Sulfate in the blood. It is produced by the adrenal glands and contributes to the production of testosterone and estrogen.
Suspected adrenal hormone overproduction
Detection or monitoring of adrenal tumors
In women: hirsutism, severe acne, menstrual irregularities, infertility evaluation
In children and adolescents: early or delayed puberty
Elevated DHEA-S levels help differentiate the source of excess androgens, whether they originate from the ovaries or the adrenal glands.
The test is used to evaluate a patient’s response to treatments related to:
Adrenal gland disorders
Polycystic Ovary Syndrome (PCOS)
Abnormal DHEA-S levels may be associated with:
Chronic fatigue
Mood disorders
Depression
DHEA-S testing is often included in a full hormonal evaluation to assess:
Adrenal gland function
Sex hormone balance
Low DHEA-S levels indicate reduced production of adrenal androgens and may be associated with:
Symptoms may include:
Severe fatigue
Muscle weakness
Weight loss
Low blood pressure
Dizziness
Conditions such as:
Liver disease
Kidney disease
Chronic inflammatory disorders
may reduce DHEA-S production.
A natural decline in DHEA-S levels occurs after the age of 40 as part of normal hormonal aging.
Medications such as Prednisone or Hydrocortisone suppress adrenal hormone production.
Pituitary dysfunction (e.g., low ACTH levels) can lead to reduced adrenal stimulation and lower DHEA-S levels.
⚠️ Note: Low levels do not always indicate a serious condition but require comprehensive medical evaluation.
Fasting is usually not required
Morning testing is preferred for optimal accuracy
Inform your doctor about all medications and supplements
A venous blood sample is drawn from the arm
Mild pain or a brief needle prick may be felt
Blood serum is separated
A specific immunoassay is used to measure DHEA-S accurately
No special care is required
Mild bruising or tenderness may occur at the puncture site
Mild pain or discomfort at the needle site
Small bruise or discoloration
Dizziness or nausea (more common in fasting individuals or those afraid of needles)
Local infection (very rare)
Anxiety related to abnormal results, which may indicate:
Adrenal gland disorders
Sex hormone imbalances
Polycystic Ovary Syndrome in women
✔️ Completely safe, as it involves only a blood draw.
Stay well hydrated
Eat a light meal unless fasting is required
Wear comfortable clothing
Inform your doctor about medications and supplements
Sit or lie down to avoid dizziness
Relax your arm and breathe deeply
Apply pressure to the puncture site for several minutes
Keep the arm elevated briefly
Avoid heavy lifting immediately afterward

⚠️ Important: Abnormal results are not always a sign of serious disease but require proper medical interpretation.
| Age Group | Normal Range (µg/dL) |
|---|---|
| 18–19 years | 145 – 395 |
| 20–29 years | 65 – 380 |

PCOS
Excessive hair growth (hirsutism)
Severe acne
Medication or supplement use (e.g., DHEA supplements)
Associated symptoms:
Menstrual irregularities

⚠️ Important Note:
Elevated DHEA-S alone is not sufficient for diagnosis. Results must be interpreted alongside:
Clinical symptoms
Other adrenal and sex hormone tests
In cases of markedly elevated levels, imaging studies and specialized adrenal evaluation may be required.
