What Is an Endomysial Antibody, IgA Test?
The endomysial antibody IgA test is a blood test that detects specific immune proteins called IgA antibodies, which the body produces when the lining of the small intestine is under attack. It is most commonly ordered to help diagnose coeliac disease, an autoimmune condition triggered by gluten. Also known as the EMA IgA test, EMA antibody test, or anti-endomysial antibody test, it uses a small sample of blood drawn from a vein.
What Does an Endomysial Antibody, IgA Test Measure?
This test looks for one specific marker in the blood. The table below explains what is measured and why it matters:
| Parameter | What It Detects | Why It Matters |
|---|---|---|
| Endomysial Antibody, IgA | IgA antibodies targeting endomysium, a connective tissue in the intestine | Elevated levels indicate the immune system is reacting to gluten, pointing to coeliac disease or a related condition |
When someone with coeliac disease eats gluten, their immune system mistakenly targets the endomysium. The presence of these antibodies signals that this damaging process is occurring. The level of antibodies detected generally reflects how severely the intestine is affected.
Why Is an Endomysial Antibody, IgA Test Done?
Doctors order this test when symptoms suggest that gluten may be harming the digestive system or to confirm an earlier positive result from another coeliac screening test.
Common Symptoms That May Require This Test
Several symptoms may prompt a doctor to recommend the anti-endomysial antibody test. These include:
- Persistent diarrhoea or loose stools
- Abdominal bloating and stomach pain
- Unexplained fatigue and low energy
- Unintentional weight loss
- Joint pain
- An itchy, blistering skin rash (dermatitis herpetiformis)
- Anaemia or signs of malnutrition, particularly in children
Conditions This Test Can Help Detect
The endomysial antibody IgA test can help identify the following conditions:
- Coeliac disease, an autoimmune disorder that damages the small intestine
- Dermatitis herpetiformis, a skin condition linked to gluten sensitivity
- Confirmation of coeliac disease in patients who have already tested positive for the tTG-IgA antibody
Endomysial Antibody, IgA Test for Chronic Disease Monitoring
Once coeliac disease is diagnosed, the EMA IgA test can be useful over time. Antibody levels tend to fall when a person follows a strict gluten-free diet, so the test gives doctors a way to gauge how well a patient is adhering to dietary changes. The titre, or concentration, of IgA antibodies generally reflects the degree of intestinal damage present.
How to Prepare and What to Expect
Preparing for this test is straightforward, but there is one important dietary instruction to follow beforehand.
Do You Need to Fast?
No fasting is required before the endomysial antibody IgA test. You can eat and drink normally on the day of your appointment. However, it is essential that you continue eating gluten-containing foods before the test. A gluten-free or low-gluten diet can cause antibody levels to drop, leading to an inaccurate result. Always follow specific instructions provided by your doctor or laboratory.
Practical Tips Before Your Test
Keep the following points in mind before going for your sample collection:
- Continue eating a normal diet that includes gluten before the test
- Inform your doctor about any medications or supplements you are currently taking
- Wear a short-sleeved or loose-fitting top for easy access to your arm
Step-by-Step Procedure
The sample collection process is quick and simple. Here is what to expect:
- A trained phlebotomist cleans a small area on your inner arm with an antiseptic wipe.
- A soft elastic band is tied around your upper arm to make your veins easier to locate.
- A fine needle is gently inserted into a vein to draw a small amount of blood.
- The blood is collected into a labelled tube, and the needle is removed.
- Light pressure is applied to the site, and a small bandage or cotton pad is placed over it.
- The sample is sealed, labelled, and dispatched to the laboratory for analysis.
Factors That Can Affect Accuracy
Certain factors may influence how reliable your results are:
- Following a gluten-free or low-gluten diet before the test
- Having an IgA deficiency, a condition where the body produces very little IgA
- A haemolysed (damaged) blood sample
- Mild disease, where antibody levels may still be within the negative range
Understanding Your Endomysial Antibody, IgA Test Results
Your endomysial antibody IgA test results will be reported as negative, positive, or indeterminate. Always review them with your doctor, who will consider your symptoms, diet history, and other test findings together.
| Result | Interpretation |
|---|---|
| Negative | No antibodies detected; coeliac disease or dermatitis herpetiformis is unlikely in most cases |
| Positive | Antibodies detected; strongly suggests coeliac disease or dermatitis herpetiformis |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how the test performs:
- People with coeliac disease have a higher chance of also having IgA deficiency. Because this test relies on detecting IgA antibodies, a deficiency can lead to a false-negative result. Your doctor may order alternative IgG-based antibody tests in this case.
- If you have already reduced or eliminated gluten from your diet before testing, your antibody levels may have fallen. This can produce a false-negative result, even if coeliac disease is present.
- In early or mild cases of coeliac disease, antibody levels may not yet be high enough to register as positive.
How to Maintain Healthy Levels
The following general lifestyle tips may support gut health and overall wellbeing:
- If coeliac disease is confirmed, work with a registered dietitian to follow a strict gluten-free diet
- Attend regular follow-up appointments so your doctor can track changes in antibody levels over time
- Read food labels carefully to avoid hidden sources of gluten in processed foods

Frequently Asked Questions
The anti-endomysial antibody test is used to help diagnose coeliac disease and dermatitis herpetiformis. It is also used to monitor whether someone with coeliac disease is adhering to a gluten-free diet, as antibody levels tend to fall when gluten is removed from the diet.
The EMA antibody test has a specificity of close to 100%, making it one of the most precise blood markers for coeliac disease. However, it is slightly less sensitive than the tTG-IgA test, so both are often used together.
No, fasting is not required. You can eat normally on the day of the test. The key requirement is that you must continue eating gluten-containing foods for at least six weeks before the test to ensure your results are accurate.
A negative result makes coeliac disease less likely, but it does not completely exclude it. A small number of people with coeliac disease test negative, particularly those with IgA deficiency or mild intestinal damage. Your doctor may recommend further testing if symptoms persist.
IgA deficiency can cause the endomysial antibody IgA test to show a false-negative result, even when coeliac disease is present. In such cases, your doctor may request IgG-based alternative tests, such as the IgG tTG antibody test or the IgG deamidated gliadin peptide test, for a more reliable result.
When a person follows a strict gluten-free diet, IgA-EMA levels typically begin to decrease within six to twelve months of starting dietary treatment. Regular follow-up testing helps confirm that the diet is working as expected.
