What is the typical role of a pathologist in the medical field?

A pathologist primarily focuses on diagnosing diseases through laboratory tests and examinations of body tissues, fluids, and biopsies. They play a crucial role in interpreting laboratory results, which helps other healthcare providers make informed decisions about patient care. By studying samples under a microscope and utilizing various diagnostic techniques, pathologists provide essential insights that guide further medical intervention or treatment strategies.

The other choices represent roles that differ significantly from that of a pathologist. Performing surgeries is a task typically associated with surgeons, while administering medication falls under the responsibilities of nurses or physicians. Leading physical therapy sessions is specific to physical therapists, who focus on rehabilitation and mobility rather than diagnostic processes. Therefore, the selection of the option regarding diagnosing diseases aligns accurately with the fundamental responsibilities of a pathologist.
