  • Rapid Urease Test Kit - an overview | ScienceDirect

    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 serum, blood, …
