CVA (Calibration Verification Assessment) and CVA for CELL-DYN are assayed linearity control kits that test the upper and lower limits of three- and five-part differential hematology analyzers to determine their patient reportable range and linear performance.

CVA (Calibration Verification Assessment) and CVA for CELL-DYN linearity control kits

CVA and CVA for CELL-DYN are assayed calibration verification kits used to establish patient reportable range and measure the linear performance of hematology instruments. These kits offer instrument-specific assay values for WBC, RBC, hemoglobin and platelet parameters. CVA and CVA for CELL-DYN are available in vials with pierceable caps for autosampling and have five-day open-vial stability, which allows CVA to be rerun if an instrument problem is detected.
