  • Rapid Urease Test Kit - an overview | ScienceDirect Topics

    The potent urease activity of the bacteria has been used for clinical testing of gastric biopsies and isolates, that is, the rapid urease test or CLO test. In the urea breath test, the high urease activity of H. pylori turns radioactively marked urea into ammonia and radioactively labeled carbon dioxide, which can be measured in the exhaled air. Other noninvasive methods based on the collection of …

  • Rapid Urease Test - an overview | ScienceDirect Topics

    The urease activity of H. pylori enabled the development of a variety of diagnostic tests, including the rapid urease test (RUT). Urease catalyzes the hydrolysis of urea into ammonia and carbon dioxide. The production of ammonia leads to an increase in the local pH. Samples are placed within a gel containing urea and a pH indicator.
