Abstract

A novel method for detecting occult blood in feces, urine, gastric juices and sputum is herein disclosed, representing an improvement in occult blood testing, particularly of the type which is readily useable by a lay person in a "self-testing" format. The method is suitable for application to a specimen predeposited in a testing zone, for example a toilet bowl. The need for specimen manipulation is eliminated. The method comprises application of an oxidizing agent preferably containing a metal chelator to the specimen of interest followed by application of a chemiluminescent or chemifluorescent compound. The ambient light is then eliminated allowing the chemiluminescent or chemifluorescent glow to be observed with the unaided eye. The chemiluminescent or chemifluorescent compounds of the invention are selected from purified sodium or potassium luminol, purified sodium or potassium benzyl (ghi) perylene hydrazide 1,2 dicarboxylic acid at a pH greater than 9.0. Using these sodium or potassium salts of hydrazides produces chemiluminescence with occult blood of such intensity that the results may be read with the unaided eye, thus eliminating the need for detection equipment.
