[ We claim:] [1.] A diagnostic apparatus for estimating an active Helicobacter pylori infectious agent in human saliva, comprising in combination an immunoassay chamber comprising a reaction membrane with immobilized antigen to said Helicobacter pylori, an absorbance layer, and a sample reservoir; a chemical reaction chamber in which said saliva is subjected to chemical analysis for an ammonia constituent thereof selected from the group consisting of ammonia, ammonium ion, and ammonium hydroxide, said chemical reaction chamber comprising a solid porous support impregnated with at least one chemical reagent indicating the presence of said ammonia constituent by a detectable change in electrical potential, in color, or in fluorescence, and said analysis comprising performing a reaction to release ammonia, whereby active Helicobacter pylori infection is diagnosed by a positive reaction of said antigen with antibody in said saliva and greater than normal level of ammonia constituent in said saliva.
