A composition for facilitating a determination that a stock solution containing a calibration or control material ("calibrator") dissolved therein has been diluted correctly, said composition comprising a stock solution having dissolved therein: a calibrator designated for use in calibrating an assay for an analyte of interest over a working concentration range; and an identifiably effective and non-interfering amount of a marker dissolved therein for identifying the dilution level of said stock solution over the working concentration range of said calibrator, said marker neither participating as a reactant nor as a label on a reactant in said assay for said analyte of interest. |
