Mother And Aunt Have Positive Aga Iga But Negative Igg

[alicewa]

Just earlier today, we found out that my mother and aunt had positive AGA IgA gliadin antibodies but negative IgG gliadin antibodies. This apparently is a very unusual reading but their stools have often been white in recent times. The doctor really wasn't sure what this meant but about once a month they get massive stomach cramps that make them pass out and they're fine the rest of the time.

For my mother, IgA was 50 but IgG was 6

How likely are they to be celiac? The tTG and DGP tests are still being processed. Both are positive for HLA-DQ2 and HLA-DQ8 genes.

When I found out I had celiac I was sicker than this and was positive for both IgA and IgG up around 130.

I have never seen any requirement for the antigliadin IgG for celiac

Just wait til the proper celiac tests come in, the ttg and DGP

[alicewa]

tTG IgA and DGP IgA and IgG are all within normal range.

Did they have a total IGA done? If they are IGA deficient the IGA tests will be a false negative for sure.

[alicewa]

Yes total IgA is normal. It was in the middle (I can't remember what number) of the range.

They were AGA IgG negative. This was all by a blood test.
