Coeliac

Coeliac disease is an autoimmune condition in which ingestion of gluten causes chronic 
inflammation of the small intestine, which can lead to malabsorption of nutrients. The test most frequently used to screen for coeliac disease measures the antibodies against tissue transglutaminase (Anti-tTG). Additional reflex tests are performed if the Anti-tTG result is positive or equivocal.
