A physician who diagnoses and characterizes disease by examining a patient’s tissues, blood, and other body fluids. Pathologists work in two broad areas:
Anatomic pathology is the examination of the physical appearance and microscopic structure of tissues. Anatomic pathologists look at biopsies and organs removed at surgery (surgical pathology) as well as cells that are collected from brushings or body fluids (cytology). They also perform autopsies to investigate the cause of death (autopsy pathology).
Clinical pathology deals with the measurement of chemical constituents of blood and other body fluids (clinical chemistry), analysis of blood cells (hematology), identification of microorganisms (microbiology), and the collection, preparation and use of blood for transfusion (transfusion medicine). Clinical pathologists direct the laboratories that perform these tests and provide consultation to other doctors on the significance of test results.
