Abstract

<P>PROBLEM TO BE SOLVED: To contribute to early discovery of cancer by readily performing occult blood reaction test at home without troublesome work of currently getting medical check or mailing a sample to a hospital for the occult blood test such as fecal examination for colon cancer or sputum examination for lung cancer. <P>SOLUTION: This kit for the occult blood reaction test at home comprises a filter paper permeated with a first occult blood test reagent for checking the existence or not of occult blood in a fecal or sputum examination sample and a second test reagent to be dropped thereon. The sample is covered with the filter paper permeated with the first test reagent and pressed by a wood piece until the sample soaks into the filter paper. The second test reagent is dropped thereon. Depending on whether it is colored or not, the existence or not of the occult blood is determined. <P>COPYRIGHT: (C)2005,JPO&NCIPI
