Hematology control composition including leukocyte analogs; and methods for their preparation and use

摘要

A hematology control product comprising leukocyte analogs is described. The analogs comprise red blood cells which simulate at least two physical properties of human leukocytes. A method for making leukocyte analogs from blood cells having desired physical properties is also described. The process comprises expanding the cell volume, changing the hemoglobin content of the cell and fixing the cell. Generally, the monocyte and lymphocyte analogs leak hemoglobin from the cell while the eosinophil analog has the hemoglobin precipitated in the cell. A further method is described to use the control product to determine whether an automatic instrument is operating within manufacturer's specification.
