First Claim
1. A medical device for analyzing gases in a person'"'"'s expired breath for assisting in diagnosis of a medical condition, which device comprises:
- a spectroscopic analyzer component that obtains a patient'"'"'s breath profile that includes at least molecular identification of at least a plurality of compounds that are present in the patient'"'"'s breath;
a computer;
a memory component operably coupled to the computer; and
a database stored within the memory component containing spectroscopic breath analysis profiles, each profile characteristic of at least one of a plurality of medical conditions;
whereinthe computer is operably coupled to the analyzer component and compares the obtained patient'"'"'s breath profile, including the identified molecular compounds, to the stored database of spectroscopic breath profiles to provide information pertinent to diagnosis of the presence or absence of a medical condition.

Abstract
A medical diagnostic device for analyzing gases in expired breath. The device includes a spectroscopic analyzer component for obtaining a patient'"'"'s breath concentration profile; a computer operably coupled to the analyzer component; a memory component operably coupled to the computer; and a database stored within the memory component containing spectroscopic breath analysis profiles. Each profile is characteristic of at least one of a plurality of medical conditions. A computer program compares the obtained patient'"'"'s breath profile to the stored database of spectroscopic breath profiles, such that diagnosis of the presence or absence of a medical condition is facilitated.
