Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide.Click to see full answer. In this regard, what is the purpose of the urease test?Urease Test. Urease broth is a differential medium that tests the ability of an organism to produce an exoenzyme, called urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red.Likewise, what if rut test is positive? A positive RUT requires approximately 105 H. pylori in the biopsy sample to change the color using an agar-based test such as the CLO test (13). However, if the patient has atrophic gastritis and large areas of intestinal metaplasia, which contain few H. pylori organisms, the results will often be disappointing. Just so, how is rapid urease test done? The rapid urease test involves incubating a gastric biopsy in a urea broth that contains the pH indicator phenol red. If gastric helicobacters are present, helicobacter urease breaks down the urea; with the release of ammonia, a rise in pH and a color change occur.What does urease mean? Medical Definition of urease : a crystallizable enzyme that catalyzes the hydrolysis of urea into ammonia and carbon dioxide, is present in the alkaline fermentation of urine, and is produced by many bacteria and found in various seeds.
