Overview of the DHEA
The DHEA blood test measures dehydroepiandrosterone, an adrenal steroid hormone and precursor used in the body's synthesis of androgens and oestrogens.
DHEA is produced predominantly by the adrenal cortex, with smaller contributions from the gonads.
The test contains 1 biomarker: DHEA.
It is important to distinguish this test from DHEA Sulphate (DHEA-S).
DHEA and DHEA-S are related but separate laboratory biomarkers. DHEA-S is the sulphated, more abundant and more stable circulating form and is commonly used for routine assessment of adrenal androgen production.
DHEA itself circulates at lower concentrations and shows greater short-term and diurnal variation.
This means DHEA measurement is generally a more specialist endocrine investigation and should be interpreted according to the precise clinical reason it was requested.
Higher DHEA concentrations can occur with exogenous DHEA supplementation and selected causes of adrenal androgen excess.
Lower concentrations are non-specific and can occur with age, adrenal dysfunction or several other physiological and medical circumstances.
A DHEA result should not be used to diagnose so-called “adrenal fatigue”, which is not an established medical diagnosis.
Where genuine adrenal insufficiency is suspected, appropriate assessment generally relies on cortisol, ACTH and, where indicated, dynamic endocrine testing rather than DHEA alone.
What Does the DHEA Test Check?
This test measures 1 biomarker.
DHEA
Measures dehydroepiandrosterone, an adrenal steroid precursor involved in androgen and oestrogen synthesis. The result can contribute to specialist assessment of adrenal androgen production but should be distinguished from the separate DHEA Sulphate assay.
Who May Benefit From the DHEA Test?
DHEA measurement is generally most useful when there is a specific endocrine reason for testing rather than as a general wellness or stress marker.
People undergoing specialist adrenal steroid assessment - DHEA can form part of a broader evaluation of adrenal hormone production.
People with unexplained androgen excess - DHEA may provide supplementary information alongside DHEA-S, testosterone and androstenedione.
People with rapid development of androgen-related symptoms - Significant hirsutism, acne or virilisation may require broader adrenal and ovarian investigation.
People taking DHEA supplements - Direct measurement may help document exposure where supplementation is being medically reviewed.
People with an adrenal disorder undergoing specialist assessment - DHEA may be measured as part of a wider steroid profile.
People with previous abnormal adrenal androgen results - Further testing may help clarify an unexpected biochemical pattern.
People whose DHEA and DHEA-S need to be distinguished - Measuring the correct analyte matters because the two markers have different circulating characteristics.
People specifically advised to obtain DHEA rather than DHEA-S - This specialist test can be arranged where an endocrinologist or other clinician has requested the non-sulphated hormone.
How to Prepare
Do not stop prescribed hormonal or steroid medication without medical advice.
If the aim is to assess baseline endogenous DHEA while taking a DHEA supplement, discuss the appropriate preparation with the clinician interpreting the result rather than stopping it arbitrarily.
Symptoms and Reasons to Consider the DHEA Test
There is no symptom pattern specific to an abnormal DHEA concentration, and testing is generally guided by endocrine findings rather than non-specific symptoms alone.
Rapid or unexplained excess facial or body hair - Androgen excess can have adrenal or ovarian causes and may require targeted hormonal investigation.
Persistent severe acne with other signs of androgen excess - Adrenal steroid testing may be considered within a wider endocrine assessment.
Scalp hair thinning associated with androgen excess - Hormonal evaluation can be relevant when accompanied by other clinical features.
Menstrual irregularity with elevated androgen results - DHEA may occasionally be considered alongside more routinely used androgen markers.
Virilisation - Deepening of the voice, marked muscle changes or rapidly progressive androgenic symptoms require medical evaluation.
Previously abnormal adrenal hormone tests - Targeted DHEA measurement may help clarify a specialist steroid profile.
Symptoms in someone taking DHEA supplements - Exogenous DHEA can alter androgen exposure and should be considered during evaluation.
Fatigue, low mood or reduced energy are not specific indicators of low DHEA and should not be used to diagnose “adrenal fatigue”.
Rapidly progressive virilisation or markedly abnormal androgen results require appropriate endocrine assessment because significant adrenal or ovarian causes may need to be excluded.
How to Book Your DHEA Test
Booking your DHEA blood test with London Blood Tests is straightforward.
Choose the DHEA
Select the DHEA test and confirm that DHEA, rather than the separate DHEA Sulphate test, is the biomarker you require.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60).
Attend your appointment
A trained professional collects the required venous serum sample, with consistent timing where appropriate.
Laboratory analysis
Your serum is analysed specifically for DHEA.
Receive your results securely
Your authorised result is delivered securely and can be reviewed with a GP, endocrinologist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the DHEA test is approximately 7–10 business days after the sample reaches the laboratory.
DHEA is a specialist endocrine assay and takes longer than the separate routine DHEA Sulphate measurement.
Additional laboratory review may occasionally extend reporting.
Understanding Your Results
Your DHEA result should be interpreted using the age-, sex- and assay-specific reference interval supplied by the laboratory.
DHEA concentrations generally decline with age.
Higher DHEA can occur in people taking DHEA supplements and in some disorders associated with increased adrenal androgen production.
An isolated elevated DHEA does not identify the underlying cause and should usually be interpreted alongside DHEA-S, testosterone, androstenedione and other relevant endocrine markers.
Lower DHEA is also non-specific.
A low result does not establish adrenal insufficiency and should not be interpreted as evidence of “adrenal fatigue”.
When true adrenal insufficiency is suspected, cortisol and ACTH-based evaluation is more directly relevant.
DHEA should also not be confused with DHEA-S when comparing results or reference ranges because the two assays measure different circulating forms of the hormone.
