Celiac: Certain celiac markers can be checked in the blood and these are typically antibody tests labeled as igg and iga. CRP is a nonspecific marker of inflammation. The blood tests are pretty good markers of celiac but the best test is a biopsy of the small intestine.

Nothing really: You need to produce IgA to use the most sensitive blood test that we use to screen for celiac which is ttg-iga ab. Other tests include ema, and dgp. Regular gliadin abs should not be used as they are not very sensitive. The gold standard is a biopsy from the duodenum (small intestine).
