Abstract
The present invention relates to an improved test composition for the diagnosis of gastric ulcers, duodenal ulcers, gastritis, gastric lymphoma and gastric carcinoma by the detection of the bacteria Helicobacter pylori and the enzyme catalase associated with such conditions. The new test composition differs from the prior art agar compositions in being an aqueous solution containing hydrogen peroxide, urea, monobasic sodium phosphate and bromthymol blue as an indicator, and in being far more rapid than the prior art test compositions.
