Abstract
An apparatus for measuring metabolites contained in human expired air and for measuring metabolites contained in human urine and for extracting a correlation between the metabolite data in the expired air and the metabolite data in the urine is suitable for parallel analysis of the metabolites in human urine and expired air. An atmospheric pressure ionization mass spectrometer is suitable for measuring metabolites in the expired air. By storing reference data showing the relation between the metabolites in the expired air and those in the urine and, by comparing such data with a subject's metabolite data in the expired air and the metabolite data in the urine, abnormality of a subject can be detected.
