METHOD FOR EVALUATING GASTRIC MUCOSAL STATE BY QUANTIFYING <I>HELICOBACTER PYLORI</I> ANTIGEN IN FECES

摘要

It is intended to provide a method for evaluating the gastric mucosal state which can be conveniently carried out while loading little burden on a subject, shows missing cases at an extremely low ratio, and enables detailed classification of not only the gastric mucosal states with the pathological severity but also the risk of gastric cancer and the risk thereof in future. It is also intended to provide a method for quantifying Helicobacter pylori cells occurring in the stomach in relation to the judgment of various pathological conditions. The above-described problems can be solved by a method for evaluating the gastric mucosal state of a subject by using a quantitative measurement value of Helicobacter pylori antigen occurring in the feces of the subject as an indication and a method of quantifying Helicobacter pylori cells occurring in the stomach of the subject.
