Comparison of Abbott fluorescence polarization immunoassay (FPIA) and Roche radioimmunoassay for the analyses of cannabinoids in urine specimens.
Abbott fluorescence polarization immunoassay (FPIA) and Roche Abuscreen radioimmunoassay (RIA) were compared qualitatively with 142 urine specimens containing 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid. Similar qualitative results were obtained in 132 specimens. When discrepent results were observed, all negative results were within 20% of the 100 ng/mL cut-off. We concluded that FPIA and RIA give comparable results to each other.
