pathologist

This term identifies a highly specialized physician who operates primarily in a laboratory setting rather than in direct patient-facing clinical care. The role is characterized by a diagnostic focus, where the professional acts as a consultant to other doctors by providing the definitive cellular or molecular evidence needed for a diagnosis.

Because the term refers to a specific professional title, it follows standard English countability rules for occupations. It is used to describe both the individual practitioner and the broader professional category within the medical hierarchy.
