Not exactly: The usual blood test for celiac disease (gluten sensitivity) is tt-g (tissue transglutaminase) antibody and serum iga. The serum IgA can pick up people with IgA deficiency. Some of these people are prone to recurrent infections like ear, sinus and respiratory infections. Many people who lack serum IgA are perfectly healthy. These tests do not identify cancers.
