Differential white cell counting on the Coulter Counter Model S Plus IV (three population) and the Technicon H6000; a...

Simple and multiple regression analyses have been used to see which of the differential white count measurements on the Technicon H6000 could be used to predict the differential white count measurements on the Coulter Counter Model S Plus IV (three population). The S Plus IV lymphocytes are predicted by the Technicon H6000 lymphocytes plus 39% of monocytes. The S Plus IV granulocytes are predicted by the Technicon H6000 neutrophils plus most of eosinophils, plus 43% of large unstained cells. The S Plus IV mononuclear cells are predicted by 5% of the Technicon H6000 lymphocytes plus 41% of monocytes, plus basophils, plus most of the large unstained cells plus 31% of eosinophils.
