Usefulness of the combined IgG and IgA antibody determinations for serodiagnosis of Helicobacter pylori infection.

Abstract

The IgG ELISA Helico-G and IgA ELISA GAP, taken separately, are good and reliable tests for the detection of antibodies to H. pylori. Furthermore, the combined use of both serological methods provided more useful information compared with single IgG and IgA determinations.
