摘要： A method for determining the presence of occult blood in the bowl of a toilet containing water and fecal matter includes the steps of applying a developing solution to a sheet of absorbent paper impregnated with a guaiac reagent to form an activated test sheet of paper, and contacting the test paper with the water in the toilet bowl. Preferably, the test sheet is an absorbent paper impregnated with a guaiac reagent and having only a portion thereof additionally impregnated with blood in an amount sufficient to react with the guaiac in the presence of a developing solution to dye the paper blue. The blood impregnated portion of the sheet upon use forms a dyed test strip with which the person using the paper can make a comparison to determine whether and the extent to which the actual guaiac reaction has taken place on the remaining portion of the sheet.
