Frequently Asked Questions
What is Endomysial Antibody IgA used for?
It is a serological marker used primarily to screen for and support the diagnosis of celiac disease. Positive results typically prompt further evaluation including tissue transglutaminase (tTG) testing and endoscopy.
Is fasting required for this test?
No, fasting is not required for Endomysial Antibody IgA testing. The sample can be collected at any time of day.
What does a positive EMA IgA result mean?
A positive result indicates the presence of IgA antibodies targeting the endomysium, strongly suggesting celiac disease. However, confirmation usually requires a duodenal biopsy as EMA IgA alone is not diagnostic.
Can a normal gluten diet affect the result?
Yes. Patients must be on a gluten-containing diet for adequate antibody production. A gluten-free diet may produce false-negative results, so testing should be done before dietary changes.
How long does it take to get results?
Reports are typically available within 24–48 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
Who should get this test done?
Individuals with chronic diarrhea, bloating, unexplained iron-deficiency anemia, weight loss, or family history of celiac disease should consult their physician for EMA IgA screening.
