H pylori diagnostic breath tests rely on a simple chemical reaction which is based on the natural behaviour of the bacteria. Naturally occuring gastric urea is made up of 99% carbon isotope 12C and 1% carbon isotope 13C. The breath test uses urea enriched with 13C (that is, 99%).

Patients first drink a sachet of orange juice or citric acid. This rapidly closes the duodenal sphincter to contain the stomach contents. They are then asked to blow through a straw into a glass tube with a screw cap lid. This provides the baseline sample.

Next, they consume a drink containing 13C enriched urea (about 100 ml) and after 30 minutes repeat the blowing exercise into a second tube. This provides the post-dose sample. Both samples are sent away for carbon dioxide isotope analysis by mass spectrometry (laboratories usually return the results within a few days).
