Thus, they are found to be larger than normal mature blood cells, and immature in their nuclear complexity and in the extent of their cytoplasmic granularity. In certain clinical or even physiologic conditions, LICs, not fully matured, especially in terms of their size and complexity, may get released into the peripheral blood. This subset consists of various immature forms of myeloid or lymphoid cells combined. LICs are a minor subset of WBCs normally found in bone marrow tissue where the hematopoiesis takes place. This allows accurate defining two additional parameters for leukocyte populations: Atypical lymphocytes (ALY) and Large Immature Cells (LIC), reported in percentage as well as absolute counts. Yumizen hematology analyzers are characterized by their capacity to manage precisely whole blood volumes added to their high level of automation. In this matrix, optical extinction (Y-axis) is plotted against volumes (X-axis) to form an image with several clusters of cells. Apart from basophils, these can be visualized on the LMNE Matrix (Figure 1) of Yumizen hematology analyzers. There are five types of leukocytes (lymphocytes, monocytes, neutrophils, eosinophils and basophils). A differential can also detect immature white blood cells and abnormalities, both of which are signs of potential issues. WBC differential determines the percentage of each type of white blood cell present in the blood. White blood cells, or leukocytes, are an important part of body's immune system as they are responsible for protecting the body against infections and invading organisms. Many new hematology parameters have been added by instrument manufacturers, some with just different terminology but similar clinical value as have been available earlier. The current generation of hematology analyzers is equipped with new and improved specific parameters, which are useful to clinicians not only for diagnostic information, but also providing invaluable prognostic value for their patients. The selection of analyzers with a variety of technological principles and techniques is made further complex due to the addition of new parameters and their specific utility throughout the patient care process. Only with just few exceptions, most of the manual methods are replaced by automated particle counter methods. Red Blood Cells (RBC), White Blood Cells (WBC) or platelets from manual and automated cell counters is central to the diagnosis and management of hematologic diseases.
