It is well-known that anti-tTG IgA is the most specific and sensitive serological marker for CD (8–10), and such a very strong correlation and concordance between CytoBead CeliAK assay and the usual methodic (single-parameter ELISA) suggests that the former assay can be safely used in the CD screening process as well as the latter one. Here, CD79A is linked to Cowden disease.
