Modification and evaluation of Abuscreen OnLine assays for drug metabolites in urine performed on a COBAS FARA II in comparison with EMIT d.a.u. Cannabinoid 20.
OnLine assays for cannabinoids, barbiturates, opiates, and cocaine from Roche Diagnostics were run on the automatic analyzer COBAS FARA II. The assay programs and the cutoff definition were modified to obtain maximum sensitivity and reagent economy. The limits of detection and curve stability data of the modified assays were compared with the original, as well as with EMIT d.a.u. Cannabinoid 20 assay, and the modified assays were found to be more favorable. Modified OnLine assays appear to be a convenient and cost-effective method for drug screening in urine.
