“What blood tests can diagnose celiac disease?”
My doctor thinks that I have celiac disease, so along with a biopsy, he would also like me to have a blood test to help confirm it. What blood tests diagnose celiac disease?

Ordering a serologic test to check for antibodies is usually the first step. The serologic test will check for IgA antibodies, specifically tTG-IgA will be positive in 93% of cases with Celiac disease who are on a gluten-containing diet. Also, genetic testing for human leukocyte antigens (HLA-DQ2 and HLA-DQ8) can be used to rule out Celiac disease. Thank you.
