Urea Breath Test

The urea breath test (UBT) is a noninvasive test utilizing 13C urea to detect the prescence of Helicobacter pylori (H. pylori) in the gut. H. pylori is a spiral bacterium that can cause gastritis, gastric ulcers, and peptic ulcers. It affects more than 50% of the global population and is one of the most prevalent chronic bacterial infections. The test can be used to aid the diagnosis of H. pylori infection or to assess the impact of a therapeutic intervention, when administered more than a month after treatment completion. H. pylori has the ability to convert urea to ammonia and carbon dioxide, so by administering a patient with 13C urea and then analyzing exhaled 13C carbon dioxide using isotope ratio mass spectrometry (IRMS), the presence of the bacteria can be determined. CIL is proud to manufacture and supply the most critical reagent for this test, 13C urea (cGMP), to hospitals and laboratories around the world. As the global demand for the UBT continues to grow, the need for additional 13C urea does as well. CIL is currently undergoing a large expansion of 13C production to prepare for future needs of this key reagent. If you are in need of a reliable commercial partner for your UBT developments, please inquire.
