Cytopathology
Cytopathology is used to aid in the diagnosis of cancer as well as the investigation of some infectious diseases and other troubling disorders. Cancer Instead of focusing on complete tissues like histopathology does, cytopathology does testing on free cells or tissue fragments. Because the specimens can be covered by a glass microscope slide for subsequent recoloring and minute scrutiny, cytopathology tests are frequently referred to as "smear tests." In any event, there are a number of procedures to determine the results of cytology testing, including cytocentrifugation. Tumor detection may also be accomplished using several smear test types. It is referred to as a cytological smear in this sense.
