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.
