A Pathologist is a physician who examines the tissues and checks the accuracy of lab tests. Pathologist plays a very important role in the health care of a patient. In a pathology, various laboratory tests are conducted on the samples of a patient that facilitate the patient’s diagnosis and treatment. Pathologists typically work in one of three main areas of discipline: as teachers, investigators, or diagnosticians. The ability to integrate clinical data with biochemical, molecular, and physiological laboratory studies is fundamental to the work performed on a daily basis. Investigators in the field of pathology use laboratory science for disease models, clinical studies, and other experimental programs to further advance the field knowledge, understanding, and treatment options for various diseases. This information is used to both treat and diagnose patients more aggressively in the future. Professionals who work in clinical laboratories or medical settings practice as consulting physicians who develop and apply their knowledge of laboratory and tissue analysis in order to diagnose and treat disease in patients. It's important to note that professionals who work in the medical industry may also work with patients in the postmortem phase. Research with these patients is used to study disease, or determine if a death was a homicide or from natural causes. The types of Pathologists are Anatomical Pathologist, Clinical Pathologist, Forensic Pathologist, Cytopathologist, Neuropathologist, Molecular Pathologist, Chemical Pathologist, Genetic Pathologist and Immunopathologist. The duties performed by Pathologist includes to make diagnoses using a microscope. They also do indulge in trying to find out what diseases are affecting living patients. They do testing and the amount of quality control involved in a diagnosis. They use laboratory tests to monitor the health of patients with chronic conditions.
