I just got back my test results and this is what they said:
Gliadin AB, Iga (GLIAD IGA) - 1 units (0-19 being negative)
TISS TRANSGL IGA (TTG IGA) - 1 Units (0-19 being negative)
IMMUNOGLOBULIN A - 19 mg/dl (68-378 being normal)
So, while my immunoglobulin level is really low/deficient, are my other test levels low enough to assume that I'm still negative or does having 19 mg/dl of IgA mean that those two other tests are basically useless? I guess the logical part of my brain says that even with a low IgA level my scores would have been higher than 1 units. I'd greatly appreciate any input has regarding this. My GI doctor is very helpful and seems very current in his knowledge of Celiac testing, but I won't see him for a couple weeks and am slightly mentally tortured wondering if I can read anymore into this testing. I know that he wants me to get the IgG testing (I think that was what he called it). But I'm wondering if that is just a precaution or if these tests are invalid because of my being IgA deficient.
Thanks in advance for any information you can share!
