Overview of the Steroid Cell Antibody Test
The Steroid Cell Antibody test is a specialist autoimmune blood test that detects antibodies directed against steroid-producing cells.
Steroid-producing cells are found in endocrine tissues including the adrenal glands and gonads.
These tissues are involved in the production of hormones such as Cortisol, Aldosterone and reproductive steroid hormones.
Steroid Cell Antibodies can occur as part of autoimmune endocrine disease and may provide useful information where an immune-mediated cause of adrenal or gonadal dysfunction is being considered.
The test does not directly measure hormone production.
A positive antibody result therefore needs to be interpreted alongside relevant hormone measurements, symptoms, medical history and other autoimmune investigations.
Likewise, a negative result does not exclude adrenal, ovarian or testicular dysfunction caused by non-autoimmune conditions.
The Steroid Cell Antibody test costs £125.
Professional blood collection is available in clinic for an additional £35 or through an at-home phlebotomy visit for an additional £60.
What Does the Steroid Cell Antibody Test Check?
This test measures 1 specialist autoimmune biomarker.
Steroid Cell Antibody
Detects autoantibodies directed against steroid-producing endocrine cells and provides information relevant to selected autoimmune adrenal or gonadal disorders.
Who May Benefit From the Steroid Cell Antibody Test?
The test may be useful where an autoimmune cause of endocrine dysfunction is being investigated.
People undergoing assessment for possible autoimmune adrenal dysfunction - Steroid Cell Antibodies may provide supporting autoimmune information.
Women with suspected autoimmune ovarian dysfunction - The result may contribute to a broader reproductive endocrine investigation.
People with unexplained gonadal hormone deficiency - Autoimmune testing may sometimes be appropriate.
People with multiple autoimmune endocrine conditions - Autoimmune processes can involve more than one endocrine gland.
People with another autoimmune disease and unexplained endocrine abnormalities - Further antibody testing may be considered.
People whose endocrinologist has specifically requested Steroid Cell Antibodies - This is the most appropriate context for specialist antibody testing.
How to Prepare
Do not stop corticosteroids or hormone-replacement medication without medical advice.
Additional hormone testing may be needed to establish whether an endocrine gland is functioning normally.
Symptoms and Reasons to Consider the Steroid Cell Antibody Test
Steroid Cell Antibodies do not themselves cause one specific symptom pattern.
Persistent unexplained fatigue or weakness - Adrenal and hormonal conditions are among many possible causes.
Low blood pressure or recurrent dizziness - Adrenal dysfunction is one potential cause requiring appropriate assessment.
Unexplained weight loss - Can occur with several endocrine and non-endocrine conditions.
Salt cravings - May occur in adrenal insufficiency but are not diagnostic.
Changes in skin pigmentation - Can occur in primary adrenal insufficiency and requires clinical assessment.
Irregular or absent menstrual cycles - Gonadal hormone dysfunction is one possible cause.
Premature loss of ovarian function - Autoimmune investigation may be relevant in selected cases.
Reduced libido, fertility problems or sex-hormone abnormalities - Wider endocrine assessment may be required.
Severe weakness, vomiting, dehydration, very low blood pressure, collapse or confusion can occur during an adrenal crisis and requires urgent medical care.
Steroid Cell Antibody testing should not delay emergency assessment where acute adrenal insufficiency is suspected.

When Will I Receive My Results?
Results are generally expected within approximately 2 working days after laboratory receipt.
Occasional repeat or confirmatory analysis may extend the reporting timeframe.
Understanding Your Results
A negative result means Steroid Cell Antibodies were not detected according to the laboratory method.
This does not exclude adrenal or gonadal dysfunction because many endocrine conditions are not autoimmune.
A positive result indicates detectable autoimmune antibody activity against steroid-producing cells.
The clinical significance depends on symptoms, other autoimmune conditions and measurements of the relevant hormones.
Further investigations may include Cortisol, ACTH, adrenal antibodies, reproductive hormones or other specialist endocrine tests depending on the clinical situation.
A positive antibody result should therefore be treated as one part of the wider endocrine assessment rather than a diagnosis by itself.
