Document Summary
Title Alternative tests for food allergy
Description Alternative tests for food allergy
Creation Date 26 June 2001
Doc type Article
Document Abstract:
Controversy surrounds the topic, due to practitioners incorrectly labelling food intolerance (non-immunological) as an allergy (immune mediated hypersensitivity). The classical, rapid Type 1 allergic reaction, which is IgE mediated can be tested for conventionally with the Skin Patch test and Skin Prick test (1), Radioallergoabsorbant (RAST) Test. IgG mediated tests (FAST & ELIZA) are unreliable due to false negative and positive reactions (2); positive tests may not be clinically relevant and hence the increased popularity of "alternate" methods as patients find their own way.
