Instrument for parallel analysis of metabolites in human urine and expired air
First Claim
1. An apparatus for parallel analysis of metabolites in human urine and expired air comprisingmeans for measuring expired air to determine metabolites in the expired air of a person to be examined,means for measuring urine to determine metabolites in the urine of the person to be examined which is substantially simultaneously sampled with the sampling of the expired air of the person;
- means for storing data of metabolites in the expired air measured by the expired air measuring means and data of metabolites in the urine measured by the urine measuring means, andcorrelation extracting means for generating a correlation between the metabolites in the expired air and the metabolites in the urine from the metabolites data.

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.

15. An apparatus for parallel analysis of metabolites in human urine and expired air comprising:
-
expired air measuring means for measuring acetone in an expired air from a subject; urine measuring means for measuring catechol amine contained in the urine of the subject which is sampled at the time of sampling the expired air of the subject; storing means for storing data of measured acetone and measured catechol amine of the subject and for storing reference data showing a relation between the acetone contained in the expired air and the catechol amine contained in the urine as to diabetes; and comparison means for comparing stored subject data of the acetone in the expired air detected by the expired air measuring means and the catechol amine in the urine detected by the urine measuring means with the stored reference data showing a relation between the acetone in the expired air and the catechol amine in the urine so as to detect an abnormality of the subject.
