[Value of the histamine liberation test in the diagnosis of intestinal protein intolerance].

The validity of the histamine releasing test for the diagnosis of cow's milk, soy, and egg protein allergy was checked in 31 infants with clinical features of intestinal protein intolerance. The test was positive in 12 of the infants, but in only 5 resp. 1 among them the prick or the Ouchterlony test were pathological. The remaining 19 infants reacted negatively in all 3 tests and subsequently tolerated oral protein loading. The results indicate the superiority of the histamine releasing test in comparison to the conventional prick- and Ouchterlony test.
