Serum levels of IgA and IgG antigliadin antibodies were evaluated in 267 subjects by using both the classic enzyme-linked immunosorbent assay and a rapid test (strip-AGA test) performed on a drop of whole blood. This new test was easy to perform and gave results comparable to those of the enzyme-linked immunosorbent assay; it could be useful in screening for celiac disease in both at-risk and normal populations.
