An area which includes a number of distinct but interrelated medical specialities that diagnose disease, mostly through analysis of tissue, cell, serum, whole blood and body fluid samples.

Pathology is a significant field in modern medical diagnosis and medical research.
Tests significance: Pathology is a medical specialty that determines the cause and nature of diseases by examining and testing body tissues (from biopsies and pap smears, for example) and bodily fluids (from samples including blood and urine).
