Celiac disease: diagnosisPOINT OF CARE TEST
• Celiac autoantibodies can be detected with a simple IgA self-tG antibodies
• Contrary to conventional serum EMA and tTG-ab tests, self tTG required no external purified or recombinant celiac antigen (endogenous erythrocyte self tTG)
•POCT is very easy to perform, does not need specialized healtcare professional
• Result are available in 5 minutes

Self transglutaminase-based rapid coeliac disease antibody detection by a lateral flow methodT. Raivio et al
Results (2)Sensitivity, specificity, positive and negative predictive value and efficiency of the IgA-class rapid whole blood test, serum tissue transglutaminase antibody (tTG-ab) and serum endomysium (EMA) tests on stored samples in the laboratory.
Comparison of on site rapid whole blood test results and serum endomysial antibody (EMA) and tissue transglutaminase antibody (tTG-ab) test results when patients under coeliac disease suspicion were investigated prospectively
