Abstract

AbstractThe clinical tests of device based on Metal Insulator Semiconductor Field Effect (MIS-FE) gas sensor for Helicobacter pylori infection diagnostics (HP-infection) are done by breath test method. This method is based on detecting increase ammonia concentration in patient’s exhaled air after reception of carbamide water solution. The device’s stable operation is based on MIS-FE gas sensor’s high sensitivity to ammonia, sensor’s parameters stability as well as especially developed two channels gas sampling system.KeywordsHelicobacter pylori infectionAmmoniaBreath (respiratory) testGas sensorField effect
