H. pylori breath test. Pylobactell 13-C urea breath test kit to diagnose gastroduodenal Helicobacter pylori infection. Next to the box is a carton of orange juice, which is taken before the test to prevent gastric (stomach) emptying. At the start of the test the patient breathes out into sealed tubes (white lids) to give a before sample. They then drink a solution of 13C-urea, a compound containing a rare stable isotope of carbon (13C). Any H. pylori bacteria present will metabolise this urea, creating 13C labelled carbon dioxide as a waste product, which will be detected in the post sample breath tests (red lidded tubes). H. pylori is a bacterium commonly found in the mucus lining of the stomach. It causes gastritis and is also the most common cause of stomach ulcers.
