Abstract

A system is provided that detects the odor of air exhaled from a subject. Based on affection information and the odor, the system indicates features of the exhaled air related to a disease based on measurement information in which the affection information indicates affection or non-affection. The system also detects the odor in the air from a medical examinee. Based on the measurement information and the features, the system determines the possibility that the medical examinee will be affected with a disease.
