IMMUNOASSAY FOR H. PYLORI IN FECAL SPECIMENS

摘要

1. A process for the determination of H. pylori in a fecal specimen which comprises: (a) dispersing a fecal specimen suspected of carrying H. pylori in a sample diluent; (b) contacting the fecal specimen in the diluent with a first polyclonal antibody for H. pylori antigen to form a complex of the antibody and the antigen; (c) separating said specimen and said complex; (d) exposing the complex to a second polyclonal antibody for said antigen and a portion of the antibody reacting with said complex, one of said first and second antibody being bound to a solid carrier and the other being labelled with a detection agent; and (e) determining the amount of the labelled antibody and in turn determining the presence of H. pylori antigen in said fecal specimen.
