Automated differential leucocyte counting by the Geometric Data Hematrak system: eighteen months experience in a private pathology laboratory.
The Geometric Data Hematrak is a computerized electronic pattern recognition system designed to scan Wright's stained blood films. The instrument consists of a microscopy and data processing computer which classifies leucocytes by a digital image processing system into various cell types. Additional features include facilities for automatic appraisal of red cell morphology and estimation of platelet numbers. We report our experience with the routine use of a Hematrak Model 360 over an 18 mth period, during which time approximately 60 000 blood films have been processed by this system.
