What is an EMA blood test?
The anti-endomysial antibody test (EMAIgA), EMA-IgA, is very specific for celiac disease. It’s estimated that a person with an elevated titer of EMA is almost assured of having celiac disease. However, the EMA test isn’t as sensitive as the tTG-IgA test; about 5-10% of celiacs do not have a positive EMA test. May, 2013
