Pathology is the study of disease using body tissue and cells. This study, performed by pathologists—medical doctors who specialize in pathology—can be performed by examining tissues with the naked eye, examining stained cells with a microscope, or analyzing the cellular or chemical composition of body fluids. Pathologists work with other members of the medical laboratory team (pathologists’ assistants, clinical laboratory scientists, and phlebotomists), as well as the clinical care team (physicians, nurses, radiology, and pharmacy) to provide diagnoses which determine treatment plans and care options.
