A complete blood count (CBC) is a set of medical laboratory tests that
provide information about the cells in a person's blood. The CBC
indicates the counts of white blood cells, red blood cells and
platelets, the concentration of hemoglobin, and the hematocrit (the
volume percentage of red blood cells). The CBC is often carried out as
part of a medical assessment, and can be used to monitor health or
diagnose diseases. The results are interpreted by comparing them to
reference ranges, which vary with gender and age. A landmark in the
automation of blood cell counts was the Coulter principle (1953), which
uses electrical impedance measurements to count blood cells and measure
their sizes. This technology remains in use in many automated analyzers.
Further research in the 1970s involved the use of optical measurements
to count and identify cells, which enabled the automation of the white
blood cell differential.
