CDS Hematology Calibrator

CDS Hematology Calibrator is manufactured for calibration of multi-parameter hematology analyzers for WBC, RBC, Hgb, MCV, Plt and MPV, as applicable to the analyzer system. Multi-parameter hematology analyzers require periodic calibration in order to produce accurate results on patient samples. Calibration may be accomplished by transferring calibration factors to the analyzer through fresh blood samples that have been assayed by reference methods. However, a more direct and convenient approach is to use a calibrator material such as CDS Hematology Calibrator, having system-specific assigned values, derived from a carefully calibrated analyzer or group of analyzers.CDS Hematology Calibrator assigned values are derived from replicate analyses on whole blood calibrated hematology analyzers (see reference procedures). Replicate analyses are performed on the user’s analyzer and calibration factors are computed by comparing recovered values and assigned values. The CDS Hematology Calibrator values are then divided by these determined factors to provide calibration settings for making adjustments to the instrument. Hct, MCH, MCHC, RDW and the WBC differential parameters do not require calibration.
