Reference Values

The presence of H. pylori results in hydrolysis of urea solution by urease produced by H. pylori, resulting in a colour change due to pH change which occurred due to hydrolysis of neutral urea to alkaline ammonia (usually from yellow to red). In infected tissues, the change in colour occurs within about 1 hour.
