They should familiarize themselves with common causes of lymphocytosis and also recognize alarming features that would prompt additional investigations. All hematologists should review the peripheral blood smear and obtain a peripheral blood flow cytometry if needed.
How do lymphocytes and phagocytes destroy pathogens?
The phagocytes membrane surrounds the pathogen and enzymes found inside the cell break down the pathogen in order to destroy it. As phagocytes do this to all pathogens that they encounter, they are called ‘non-specific’. Lymphocytes are another type of white blood cell. They recognise proteins on the surface of pathogens called antigens.
