Gluten Intolerance Blood Test

(Orange)

I am wondering if there is a test for gluten intolerance. I know that there is one for Celiac... but how do people identify gluten intolerance.

I have had a IGA and IGG test which shows low levels of irritation, but when I am on a gluten free diet I feel much healthier and better?

Could it be I am not allergic? May I be allergic to something else?

Is there some other sort of blood test I could take that would give me conclusive results?
