A process for the determination of H. pylori in a fecal specimen comprising (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 labeled with a detection agent; and (e) determining the amount of the labeled antibody and in turn determining the presence of H. pylori antigen in said fecal specimen.

Immunoassay for H. pylori in fecal specimens

A method for staining fecal specimens to diagnose stool parasites preserved with a non-mercury fixative wherein the preserved specimen is stained with a composition of iron hematoxylin stain and trichrome stain.

Method for staining stool parasites

A process for the determination of H. pylori in a fecal specimen which comprises; (a) collecting a smear of a fecal specimen on a substrate; (b) immersing at least the portion of the substrate carrying the smear in a sample diluent so as to disperse the fecal specimen in the diluent; (c) 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; (d) separating the specimen and the complex; (e) exposing the complex to a second polyclonal antibody for the antigen and a portion of the antibody reacting with the complex, one of said first and second antibody being bound to a solid carrier and the other being labelled with a detection agent; and (f) determining the amount of the labelled antibody and in turn determining the presence of H. pylori antigen in the fecal specimen.
