[Significance of anti-gluten IgA levels for detection and monitoring of celiac disease].

Diagnosis of coeliac disease rests in jejunal biopsy. This is recognised as a traumatic examination which today may perhaps be replaced by a biological test produced by Pharmacia in which the anti-gluten IgA is measured by the ELISA method. The sensitivity of the test reaches 100% and the specificity to 96%. This biological test makes it possible to follow the development of the coeliac illness under diet, since the anti-gluten IgA diminishes significantly, often to the normal level.
