Abstract

An alternative approach to the problems inherent in current methods for detecting Helicobacter pylori carriers-that of being generally time-consuming, expensive, and not sufficiently sensitive-was devised by using the urea concentration and pH levels of gastric juices. A linear discriminant analysis of these variables, measured in 54 patients submitted to digestive endoscopy for gastritis, provided a mathematical formula for assigning the subjects (previously classified by other standard methods) to groups of either positive or negative H pylori carriers. The results obtained showed a correct classification in 52 out of 54 cases with only one false negative and one false positive case.
