The finding of tTG IgG antibodies may indicate a diagnosis of celiac disease, particularly in individuals who are IgA deficient. I generally eat keto, but have been cheating a lot recently due to gestures at everything. The reference range for TTG IgA will vary depending on the hospital. Although the sensitivity and specificity of this test is high, tTG can be present in as many as 5% of control patients. Get the latest research information from NIH: You have reached the maximum number of saved studies (100).
IgA anti-tissue transglutaminase (tTG) and IgA anti-endomysial antibodies (EmA). adult patients, both genders, aged between 18-70 years; with suspected CD (i.e. Celiac disease affects approximately 1% of the worldwide population.

I got a weak positive blood test the first time because I wasn’t eating a ton of gluten before the test. Text in brackets [ ] above was added by Melinda Dennis. The present study is performed to investigate the clinical usefulness of the in vitro production of EmA in CD diagnosis in a large number of consecutive adult patients with suspected CD and weakly positive [e.g. – https://www.ncbi.nlm.nih.gov/pubmed/8783752/ affected with one or more of the following symptoms: chronic diarrhea or constipation, alternating bowel habits, abdominal pain, dyspepsia, recurrent aphthosis, dental enamel defects, thyroiditis, dermatitis, osteoporosis, joints pain, weight loss, anemia, cryptogenetic hypertransaminasemia); with weakly positive [e.g. U.S. Department of Health and Human Services, The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.
