TEST COMPOSITION FOR THE RAPID DETECTION OF HELICOBACTER PYLORI IN GASTRIC BIOPSY TISSUE

摘要

An improved test composition for the diagnosis of gastric disease by detecting the presence of urease associated with H. pylori in a biopsy specimen is described in which the hydrolysis of urea by said urease is detected by a combination of at least two dye indicators showing a color change and a positive result at an acid pH, in which the positive color is distinctive from the color of the biopsy specimen, and in which most positive results occur in 2-10 minutes and all occur in no more than 4 hours. Specific compositions are disclosed.
