Confused About Test's

[jjrobin]

Ok, I took my son to the Pedi GI yesterday. I have been thinking celiac disease since the allergist told me that wheat may be the culprit. I never saw the numbers, but his IgE's were 124 at 2 years old. The concentration was kU/1. Now, I am confused. The pedi GI ordered all IG's. IgE, IgA, IgG, etc. I thought they were all realted to allergy?? He also ordered CBC with white blood count differential. I mentioned celiac disease and he sat back in his chair, and hmmm'd then told me that is a definite possibility. He is also thinking parasite. So, my question is this....if his IgE's came back at 124 per kU, then why didn't the allergist run the other's? Or is this normal to run just one IG test for allergies?

Ige is the allergy test. The others you mentioned -- Igg and Igg are celiac related. Also Ttg. Celiac is not an allergy.

It definitely looks like he has a wheat allergy, but until you know the results of the IgA's and IgG's, you can't really tell if he's also gluten-intolerant... (Assuming that result is a positive - I don't remember the reference range...)

I think people are misunderstanding your question. We just went through this so maybe I can help. Our ped GI just ran the immunoglobulins as well. IgE's are most often correlated with allergies. However, you can also have allergic reations with IgA's and IgG's - those are usually delayed reactions. My daughter's IgA's were double the normal amount. The allergist and ped GI said this is often the case with intestinal infections or allergies as well as other intestinal conditions. Elevated immunoglobulins won't give you specific info...they just point you in some direction. I'd guess the ped GI would want to do anti-gliadin IgA's and IgG's as well to determine if those are elevated. Keep in mind that you have IgA's and IgG's to many different things, anti-gliadin being only one of them. I hope this helps a bit! Take care!

Celiac Disease in not an alergy, it is a gluten intolerance, very different
