Low magnification (100x) view of the feathered edge. This test is used to analyze the complete blood count. Blood smear analysis allows quantitation of the different types of leukocytes (called the differential count), estimation of the platelet count, and detection of morphologic abnormalities that may be indicators of pathophysiologic processes. The differential involves the Technician or Technologist will count 100 white blood cells (WBCS) noting the number, type and characteristics of blood cells.
