Anti-transglutaminase antibodies

Anti-transglutaminase antibodies (ATA) are antibodies found more frequently in certain autoimmune diseases. High levels (titers) of ATA are found at in almost all instances of coeliac disease. Given the association of ATA with celiac disease, and the prevelance of coeliac disease it is estimated that ~1% of the population have potentially pathogenic levels of ATA.
