Details about DHEA Sulphate
What is a DHEA Sulphate test?
A DHEA-S test measures the level of dehydroepiandrosterone sulphate in your blood, a hormone produced mainly by the adrenal glands. DHEA-S is a precursor to testosterone and oestrogen and plays an important role in stress response, energy levels, and hormonal balance.
Because DHEA-S levels decline with age and change with stress and adrenal function, this marker is useful in assessing adrenal health and hormone-related symptoms.
Why do I need a DHEA-S test?
Abnormal DHEA-S levels are commonly seen in adrenal dysfunction, chronic stress, PCOS, fatigue, and hormonal imbalance.
Reasons for testing include:
• Persistent fatigue or burnout
• Chronic stress symptoms
• Suspected adrenal dysfunction
• PCOS symptoms (acne, hair growth, irregular cycles)
• Low libido
• Hormonal imbalance
• Early ageing symptoms
• Monitoring hormone therapy
Symptoms that may prompt testing include:
• Low energy
• Brain fog
• Sleep problems
• Weight gain around abdomen
• Mood changes

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
