I recently had some of the Celiac tests taken as I have been having GI issues and my Aunt and cousin(both blood related) have Celiac Disease. I don't really know how to interperet the results. The nurse simply told me, "negative" over the phone and didn't offer any explination. Here are my results.
Immunoglobulin A: 210.00 Reference(68-378)
Tissue Transglutaminase IGG: Test not performed
Tissue Transglutaminase IGA: 5 Reference(0-19 units)
Gliadin Peptide AB, Iga: 4 Reference(0-19units)
Liver Panel
ALT/SGPT: 90 Reference(12-78)

(P.S. I do not drink alcohal at all, I did not take tylenol or ibprofin before the test and I did not work out heavily before the test. They told me that could be the reason for the liver tests)
