Neg Iga, Borderline Igg?

[Nantzie]

I got my IgA and IgG results from my doctor yesterday. They were the only celiac tests I got.

IgA was 8 (normal would be up to 25)

IgG was 23.4 (normal would be up to 30, according to her)

I've heard though that normal for both is up to 25, so I'm considering myself borderline positive on the IgG.

From what I understand from this board, these tests aren't terribly accurate and if I'm not eating enough gluten, they may not show anything.

I have ordered a TTG test kit from York Labs so I'm waiting on that.

If I remember right, IgA is more specifically geared toward celiac.

But what is IgG looking for?

IgA and IgG are more towards detecting a problem with gluten in the body.

Total Serum IgA will rule out IgA deficiency...if you are IgA deficient then the IgA testing would not be accurate so this rules that out.

tTG and EMA are more towards damage and are the more specific tests for celiac.

All of those tests should be done. I would not rule out celiac by the tests you had done.

The IgG is the least specific of all the tests.

I would also get a copy of the blood tests. Different labs have different ranges of what is normal.

They didn't do Total Serum IgA. It was anti-gliadin IgA. I'm guessing that's different?

The IgA and IgG were the only tests that she was able to find on the lab forms, of the five full-panel celiac tests.

She's still sending me to a GI specialist to get a biopsy, so maybe he can send me to a lab that can do the additional tests. That, combined with the tTG from York should give me an idea of whether I can possibly rule out celiac. No matter the test results, I'm still planning on going gluten-free to see if I have improvement just based on that.

Then if I'm not feeling better, I'm going to get some food allergy testing done to see what is going on. Because whether or not I've got celiac, SOMETHING is going on with my digestion. If it's not celiac, I'm starting to suspect that it's some type of food allergy or intolerance. And actually, even if it is celiac, I'm going to get the allergy testing done.
