Digital image analysis of blood cells

Abstract

Rapid and accurate counts of red blood cells (RBCs), nucleated RBCs, platelets, and white blood cells (WBCs) (total and differential WBCs) are important requirements for a hematology laboratory. The detection of abnormal blood cell populations and the recognition of pathologic distributions of leukocytes are also of clinical importance. Manual microscopy counts are still required when a sample is flagged by the hematology analyzer and are still the reference method for WBC differential counts. Automated microscopy analyzers can provide accurate WBC differential counts, which may replace manual microscopy, but should not replace the eye of the cytologist.
