Exhaled air Raman spectroscopy for Helicobacter pylori diagnostics

The possibility using Raman spectroscopy in the analysis of samples for the urease breath test to diagnose the presence of the bacterium Helicobacter pylori has been demonstrated. The Raman scattering spectra of the air exhaled by a person were obtained, the volume fractions of 12CO2 and 13CO2 in exhalation samples were determined.
