My son's CD was suggested by the above test, but a definitive diagnosis should
be made with the endomysial antibody blood test and ideally with an intestinal
biopsy.  While the intestinal permeability test is a medically recognized test
(used more often in Europe than in the US, I am told), it is not specific for
Celiac Disease.  It shows if the gut is too permeable, but there are other
disorders which could cause this besides CD.  For details on diagnostic
testing, send an email to [log in to unmask] with the body GET
