For decades, one of the most commonly ordered tests in the doctor’s office has been the cell blood count (CBC). Although simple and relatively inexpensive, this test is a very effective screening tool for a wide range of conditions. For example, a lower number of red blood cells could be an indicator for anemia and further investigations could identify the likely cause. A higher number of neutrophils could indicate an infection in progress, while changes in the number of lymphocytes could reveal some metabolic or proliferative diseases. The origins of CBC are linked to the discovery of chemical cell stains in the middle of the 19th century and the count was usually done manually, under the microscope, on hemocytometer slides. By the middle of the 20th century, automated measurements of electric impedance across apertures were introduced to count red and white blood cells, and size distribution within the red blood cell fraction. Currently, blood samples from patients are examined mostly using automated flow cytometers, based on principles of fluorescence or light scattering measurements, and are capable of counting not only red and white blood cells, but also the different leukocyte subsets.
