<<Disclaimer: Verify this information before applying it to your situation.>> I posted earlier about this topic & have received a few e-mails that clarified & corrected some of the stuff I said. I apparently got some of my IG's mixed up! My comments are in brackets. ~Valerie in Tacoma Responses summarized below: We have both had lots of successes with the ELISA tests and our Naturopaths. ... I believe, however, that skin tests look at IgE responses (not IgA as you said in your e-mail). IgE is the traditional allergic response. The ELISA test looks at IgE and IgG. One reason many naturopaths use the elimination diet is because there is no other way to detect IgA responses. I have never heard of a blood test that detects IgA reactions, which is why following through on the elimination diet is so important for many of us. ~Laurie [I had the ELISA food allergy tests for both IGe and IGg. IGe is supposed to test for immediate allergy responses (as Laurie says "classic") & IGg is the delayed allergy response. Some doctors don't consider the IGg response a true allergy. Whatever! It's just semantics if you ask me! I know I feel tons better now that I'm avoiding the foods I got a strong IGg reaction to. There are IGa tests for antigliadin antibodies, but I don't know if it's done by ELISA tests or another method. At any rate, it's not an allergy test, but a specific type of sensitivity to gluten.] ------------------- I also have dual allergies with my CD. Thanks so much. I have thought and thought about food testing, but was to understand it was expensive and not all that reliable. I think you made a good point on who you go to is as important as the testing itself. Thanks again. I'll let you know when I give it a try. ~Deb ------------------- This form of testing sounds like the old cytotoxic testing...used to draw blood and then expose two hundred food samples to it. White corpuscles explod when confronted with an allergic food...which explains why people with allergies are often sick. I had this test done in the seventies, and found it very helpful [testing was done by the Atkins Center in NYC], but over the years allergists have poo-pooed it. Glad to see it's coming back. I found it reliable and accurate. ~Ann [Actually this is not like that at all. ELISA testing involves flushing blood over a card in which various antigens have been implanted in dots on the surface. If the blood carries antibodies against a particular substance, the antibodies will stick to that spot causing a color change.] ------------------ [One respondant pointed out that gluten sensitivity is not an allergy. I hope I didn't give anyone the impression that they are the same. Gluten sensitivity is not an allergy, but an autoimmune response. Another respondant pointed out that some labs can test for gluten sensitivity with an ELISA test of a subclass of IGg.]
