<<Disclaimer: Verify this information before applying it to your situation.>> I had asked if anyone knew what my blood test results meant. They were: IgA <4 IgG <43 Of the people who responded, none of them agreed on an interpretation, but everyone agreed that I should ask my doctor (she says they are normal & she has since quit) or the lab that did the work (their paperwork says this is in the normal range). I also asked if people felt I should go ahead and get a biopsy done. More people said yes than no. I have decided to find a new doctor and see if I can get a biopsy done to get some definitive answers. I may also check with the lab that did the original tests, because some of the people who responded felt that my results indicated an IgA deficiency and a borderline celiac situation. My guess is that the labs are using different scales for different tests (i.e. a 4 reading at one lab is not the same as a 4 at another lab). Anyway, thanks to everyone for the emotional support. I was really at a low point and as always, you cheered me up with your concern. Thanks a million, Colby Ray Bellevue, WA
