The INNOFLUOR® Phenobarbital Assay System is an in vitro diagnostic device intended for the quantitative determination of total Phenobarbital in serum for therapeutic drug monitoring by fluorescence polarization immunoassay. The assay system is for use on the Abbott TDx® or the TDxFLx® analyzer.
The INNOFLUOR® Phenobarbital Reagent Set is intended for the quantitative determination of total phenobarbital in serum for therapeutic drug monitoring. The reagent set is intended for use in the INNOFLUOR® Phenobarbital Assay System.
The INNOFLUOR® Phenobarbital Calibrator Set is intended for use in the calibration of the INNOFLUOR® Phenobarbital Assay System.
The INNOFLUOR® Phenobarbital Reagent Set and Calibrator Set are used together to generate the calibration curve on the TDx®/TDxFLx® analyzer. The calibration curve must be established prior to assaying unknown samples. Prior to performing the calibration procedure, the correct analyzer operating parameters must be set by following the instructions provided in the Product Insert Supplement, which is included with every INNOFLUOR® Phenobarbital Reagent Set.
