Abstract
A quality control material is disclosed which is used to monitor the calibration or used for recalibration of instruments used to screen for interferents in serum or plasma specimens. In particular, the quality control material disclosed is used to monitor instrument calibrations or used for recalibration for instruments which assess the amount of hemolysis, turbidity, bilirubinemia and biliverdinemia, either separately, or any two, or any three, or all four simultaneously, in plasma or serum samples. The quality control material does not contain any blood products such as plasma lipids, bile pigments, or hemoglobin, is stable at room temperature, and is ready for use with up to four constituents.
