HELicobacter Pylori Screening in Patients With Acute Myocardial Infarction Pilot Study

The UBT is based on the fact that Hp produces urease, which catalyzes the urea molecule into ammonia (NH3) and carbon dioxide (CO2). After fasting for six hours prior to testing, the patient swallows a C13 Urea tablet or solution and waits. After 10 minutes, the patient exhales and breath is collected (tube, bag or breath card). The production of 13CO2 is measured by a desktop analyzer (infrared mass spectrometry) and Hp diagnosis is made based on previously established cut-off levels for Hp infection.
