The IgA endomysial antibody test (EMA) based on fluorescence testing on primate esophagus or human umbilical cord is based on antibody reactivity to tissue-bound TG-2. EMA is more labor-intensive and depends on personal judgment and experience.

20 gru 2021 · The EMA-IgA test is an important marker for celiac disease, portraying a 99% accuracy rate. This test is expensive and involves a high degree of technical precision. It is used as an accompanying test along with the routine tTG-IgA test to confirm the diagnosis of celiac disease.
Consequently, serum tTG and/or EMA IgA tests are commonly used to monitor patients and are often interpreted clinically as reflecting mucosal damage on a gluten-free diet. ... The diagnostic accuracy of serologic tests for celiac disease: A systematic review. Gastroenterology. 2005;128:38–46. doi: 10.1053/j.gastro.2005.02.028.
25 cze 2019 · The EmA test is regarded as the gold standard when determining the celiac disease autoantibodies, but due to its labor-intensiveness, high cost, and subjective interpretation, its use is...
IgA Endomysial antibody (EMA): The EMA test has a specificity of almost 100%, making it the most specific test for celiac disease, although it is not as sensitive as the tTG-IgA test. About 5-10% of people with celiac disease do not have a positive EMA test.
This study compared the sensitivity, specificity, and predictive value of an immunofluorescence method for anti-endomysial antibodies (EmAs) and two anti-tTG ELISAs, one using guinea pig tTG (gp-tTG) and the other human tTG (h-tTG) as antigen, in consecutive patients investigated for suspected celiac disease (CD).
23 lip 2019 · The present review is timely and provides a thorough appraisal of various aspects characterizing celiac disease. Remaining challenges include obtaining a better understanding of still-unclear phenotypes such as slow-responsive, potential (minimal lesions) and seronegative celiac disease.
