چکیده
Results: Of these patients, 141 (92.8%) had a positive tTG-IgA and 11 (7.2%) had a negative result. Eighty-one (53.3%) did not have an EGD performed due to patient or legal representatives declining. Of the 71 who had a biopsy, the result of the tTG-IgA in 29 (40.8%) was a true positive, 35 (49.3%) a false positive, 2 (2.8%) a true negative, and 5 (7.0%) a false negative. The sensitivity was 85%, specificity 5%, positive predictive value 45%, and accuracy 43.7%.

متن کاملSimultaneous Detection of IgA/IgG AntiTissue Transglutaminase/Deamidated Gliadin Peptides in Serodiagnosis of Celiac Disease
Background: Celiac disease is a common autoimmune disorder that is diagnosed based on clinical case identification, serological screening, and duodenal histology. However, the existence of mild clinical forms, such as seronegative cases with patchy atrophy and potential celiac disease, can make it difficult to determine a definitive diagnosis. The seronegative patients with celiac disease can i...
