GENERAL INFORMATION:
What is this test?
This test detects the activity of urease by measuring carbon dioxide (CO2) gas in air that is exhaled (breathed out). Urease is an enzyme produced by the bacteria Helicobacter pylori (H. pylori). This test is done after drinking a liquid that contains urea. It is used to help diagnose and manage a H. pylori infection such as H. pylori gastritis.

Lab tests may be ordered for professional or legal reasons. You may need this test if you have:
