SUSPENSIONSMEDIEN FÜR HÄMATOLIGISCHE ZUSAMMENSETZUNGEN UND METHODE FÜR IHREN GEBRAUCH

摘要

A hematology control product comprising leukocyte analogs and an aqueous solution of a plasma substance for use in a blood counting instrument is described. The instrument employs a lytic reagent system for the lysable red blood cells in the control product. The plasma substance is in an amount effective to enable the differentiation of each of said leukocyte analogs relative to the physical attributes of the analogs, said physical attributes of the analog are similar to human leukocytes. Preferably, the plasma substance comprises cholesterol or its derivatives. A method for using the cell suspension media comprising an aqueous solution of a plasma substance is also described. The method provides a quality control to determine whether an instrument is operating within manufacturer's specifications.
