My daughter was diagnosed w/ gluten sensitivity several wks ago via stool test, so I asked my dr. if I could have bloodwork to test for Celiac's.

Results:
Deamidated gliadin ABS, IgA 1.7 (normal 1-10)
Deamidated gliadin ABS, IgG 0.07 (normal 1-10)
t-transglutaminase, IgA 1 (normal 0-3, weak positive 4-10, positive >10)
t-transglutaminase, IgG 1 (normal 0-5, weak positive 6-9, positive >9)
endomysial antibody, IgA negative
Immunoglobulin A, QN, serum 60 L (normal for > 19 yrs is 70-400)

My dr read this as meaning I'm fine, while acknowledging this isn't her area of expertise. But a naturopath dr I asked about it said that b/c my IgA is low overall, the rest of the test results are invalid, unhelpful. But he didn't have much more to say than that.

Can someone point me to a good source of info to explain what all these tests are about, particularly the last one? What's next? Would IgA stool testing be similarly invalid b/c of lack of IgA? Do I need to do something about the lack of IgA? What problems could I have b/c my IgA is low? Any info helpful. Thanks.
