<<Disclaimer: Verify this information before applying it to your situation.>> Hello, It seems my blood tests were negative. I'm not too surprised. It was a shot in dark, since I've been on restrictive diets for such a long time. On other hand I really don't know how good the lab was either. From what I hear the best test is the hardest to read. There is no way on God's green earth that I will prolong my glutenfication more than what I did. So it was worth a shot anyway, but I'll just have to accept my undiagnosisability. Anyway, I have a question about the IgA and IgG. My results were: IgA = 2.9 U/I IgG= 17.7 U/ml They interpreted the IgA as negative, but didn't interpret the IgG. I looked in my resources but couldn't find any help. Does anybody know what these numbers means? It really doesn't matter much, I know I have some sort of reaction to at least wheat. So I will go GF and see if things get even better after a few months. Also I read, I think from Dr. Murry, in the diagnosis file that even if all medical tests are negative and there are still symptoms (where everythi ng else has been ruled out), a GF diet should be tried. Everythings been ruled out by my doctors at home, so we will see. lance
