Patient : I was diagnosed with a dermatitis eczema type rash that is now gone. I was concerned it may have been food related and had RAST testing done for several foods, all of which came back Class 0. I have read this test is often wrong. My question is how accurate is RAST and if all were Class 0, does this mean I can stop worrying and that I am NOT allergic to any of these foods?
