<<Disclaimer: Verify this information before applying it to your situation.>> A biopsy last August showed that I probably have Celiac Sprue. However, I have not improved in the 8 gluten-free months that have followed, and a gastroenterologist ordered Immunoglobulen blood tests (in addition to a CT scan and a follow-up biopsy in three weeks) to check for what else might be going on. I can't get his office to give me any interpretation of the results; I suppose he's waiting for the biopsy. But in the mean time I would very much like to know whether the following results support a diagnosis of celiac sprue, or suggest that something else is going on: IgG 3268 (normal 700 - 1600) IgA 15 (normal 70 - 400) IgM 4 (normal 40 - 230) IgE 2 (normal - 48) Gastrin Serum 89 (normal 25 - 111) I would be grateful for any interpretation. - Mark
