IgA and celiac
Iga type antibodies are the specific ones we are usually looking for in order to make the diagnosis of celiac disease
We can find them in blood, stool or tissues. Simply finding them in the blood is not enough to make the diagnosis for certain. If your total IgA level is low, it may distort the test result for celiac disease and make it look like you don't have it when you could have it after all.
