Analyzers, Laboratory, Hematology, Cell Counting
Definition : Laboratory analyzers used to perform complete blood counts, including white blood cell, red blood cell, and platelet count; to determine hemoglobin concentration; and also to determine the red cell blood indices (mean cell hemoglobin, mean cell-hemoglobin concentration, and mean cell volume). Some also include white cell differential counts. Hematology analyzers use several measuring methods (e.g., electrical impedance, photometric, radiofrequency conductivity) or a combination of them. Some of these analyzers also determine other parameters, such as red blood cell distribution width and mean platelet volume. These analyzers are used to determine abnormalities in red cell blood count (anemia and polycythemia), white cell count (indicating infections), or platelet count (related to blood clotting). The differential count of the white cell blood population is useful in diagnosing infections and as additional information for diagnosing such diseases as leukemia and rheumatoid disorders.
