Abstract:
1. A method for detecting occult blood in a specimen comprising: (a) treating the specimen with a reacting solution comprising a strong reducing agent selected from the group consisting of sodium borohydride, potassium borohydride, calcium borohydride, copper borohydride, ammonium borohydride, benxyltriethylammonium borohydride, benzyl-triphenylphosphonium borohydride, bis (triphenylphosphine)copper(I) borohydride, cetyl-trimethylammonium borohydride, lithium borohydride, methytrioctylammonium borohydride, tetramethylammonium borohydride, tetrabutylammonium borohydride, tetraethylammonium borohydride, lithium aluminum hydride, diborane, 9-borabicyclononane (9-BBN), dihydrogen, a grignard reagent, dialkylcopper lithium (lithium dialkylcuprate) reagents, metallic sodium, metallo-organic alkyl sodium and metallo-organic alkyl lithium; and (b) monitoring the treated specimen for fluorescence, wherein fluorescence indicates the presence of occult blood.
