My doctor's assistant sent a note in the mail saying my test indicated that I was not allergic to wheat. I called to ask for the specific results and he gave me this:

IGA plus T (266)

Ttg (4)

I was looking at everyone else's postings, but I didn't see anybody with the same description. Did I get the wrong tests? It just said "Celiac Test" on the lab form.

Hi there. I'm pretty new at this myself, and I'm still pursuing a diagnosis. Celiac Test is extremely vague. IgA and Ttg are elements of a series of tests. I don't have my Ttg results, so I can't compare them (mine came up as negative, I know that). But my lab slip shows the following range(s):

IgA: under 20 units is negative

20-30 units is weak positive

30+ units is moderate to strong positive

IgG scale is very similar, just add 4 pts.

I had both of these and they came up a weak/moderate positive respectively.

Depending on where you live, level may be based on a different scale, I'm in America.

Hope that helps a little!

The IgA plus T would probably be your total serum IgA. this test would show that you are not deficient in Immunoglobulin A, which would alther your other tests if you were deficient. It looks like a normal amount of IgA.

The Ttg test is the Tissue Transglutaminase test to check for Celiac. This is apparently the most specific blood test for Celiac, but it only is in positive range if you have a lot of damage to the intestines that have allowed the antibodies to "leak" into your blood stream. They should have also run the Anti-gliadin IgG and Anti-gliadin IgA for a complete picture. A lot of people only test positive on one of the three. Often it is only the IgG that shows positive in people who don't have a lot of intestinal damage yet.

    • It seems like you really need a concrete or near concrete answer so I would say maybe you ought to get the gene testing. Then you can decide on the gluten challenge.   Thanks! I am convinced our dogs are there waiting for us. Meanwhile they are playing, running, laughing, barking & chasing. I have another favorite quote dealing with dogs: "If a dog will not come to you after having looked you in the face, you should go home & examine your conscience."  ~~~ Woodrow Wilson ~~~
    • I can't help thinking that all of this would be so much easier if the doctor I went to 10 years ago would have done testing for celiac, rather than tell me I probably should avoid gluten. He was looking to sell allergy shots and hormone treatment, he had nothing to gain from me being diagnosed celiac. I've been messing around ever since, sort-of-most-of the time being gluten free but never being strict about it. I really feel like three months of eating gluten would do my body a lot of permanent damage. I've got elevated liver enzymes for the third time since 2008 and no cause can be found which might be good, I guess. I wonder if it would be reasonable to do the HLA testing first, to decide if I really need to do the gluten challenge. If the biopsy is negative, that is. Squirmingitch, love your tag line about dogs in heaven. We lost the best dog ever last December. I sure hope all my dogs are there waiting for me!
    • Most (90%-95%) patients with celiac disease have 1 or 2 copies of HLA-DQ2 haplotype (see below), while the remainder have HLA-DQ8 haplotype. Rare exceptions to these associations have been occasionally seen. In 1 study of celiac disease, only 0.7% of patients with celiac disease lacked the HLA alleles mentioned above. Results are reported as permissive, nonpermissive, or equivocal gene pairs. From: http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/88906  
    • This is not quite as cut & dried as it sounds. Although rare, there are diagnosed celiacs who do not have either of those genes. Ravenwoodglass, who posted above, is one of those people. I think she has double DQ9 genes? Am I right Raven?  My point is, that getting the gene testing is not an absolute determination either way.
    • Why yes it is! jmg and myself are NCIS, I mean NCGS specialist/experts or is it NCGI people ourselves. posterboy,
