Definition

  • The patient ingests C-14 or C-13 labeled urea , the clinic collects the patients exhaled breath and the lab measures the amount of the chosen isotope in the exhaled CO2. H pylori produces urease that digests urea to produce CO2. The most common isotope is C13 which is detected by infrared spectroscopy. Tagged CO2 in the breath is evidence of gastric Helicobacter pylori infection.
