METHOD FOR DETERMINING ALDEHYDE-DEGRADING ENZYME ACTIVITY GENOTYPE METHOD FOR DETERMINING SQUAMOUS EPITHELIAL CANCER ONSET RISK DEVICE FOR DETERMINING SQUAMOUS EPITHELIAL CANCER ONSET RISK AND PROGRAM

摘要

After the subjects have consumed ethanol, the subject's breath is taken and the acetaldehyde concentration and the ethanol concentration in the breath are measured. From this measured value, the ratio of the acetaldehyde concentration to the ethanol concentration is calculated. Based on this ratio, the subject's aldehyde degrading enzyme active genotype and the risk of developing squamous cell cancer are determined.;
