Abstract:
A method of assuring quality of a hematology instrument, comprising the steps of:a) providing a multi-parameter automated hematology instrument; b) providing in a known reference quantity: a. a first component for simulating human reticulocytes for detection by said multiparameter hematology analysis instrument; b. a second component for simulating human nucleated red blood cells for detection by said multiparameter hematology analysis instrument; c. a white blood cell component that is prepared from white blood cell analogs and is capable of exhibiting a five-part differential, upon detection by said multiparameter hematology analysis instrument; c) counting the population number per component type, of an admixture from said step (b), with said multi-parameter automated hematology instrument; and d) comparing the population number per component type obtained from step c) above with said known reference quantity for each component type.
