International ClassesC07D 491/16C07D 311/80 AbstractThis disclosure related to a method and reagents for determining tetrahydrocannabinoids (THC) and THC metabolites in a biological fluid such as urine. In particular, this disclosure relates to a fluorescence polarization immunoassay procedure for determining the presence of THC and to a novel class of tracer compounds employed as reagents in such procedures. The procedure described also provides for novel wash reagent for a THC fluorescence polarization assay.Other References
