The Department of Pathology and Laboratory Medicine provides a wide range of anatomic and clinical diagnostic pathology services. Board-certified pathologists, many with advanced subspecialty training, work together with physicians and laboratory technical staff to provide expert consultation on prevention, diagnosis, and treatment of human disease. It is estimated that 70% of all medical decisions are based on the results of a laboratory test. At the Brown clinical sites, clinical testing is provided by modern, fully-automated and CAP-certified clinical laboratories. Specialized testing and expert interpretation by pathologists are provided in "clinical pathology", which is predominantly the laboratory testing performed on fluids. This includes chemistry, endocrinology, cytogenetics, microbiology, transfusion medicine, coagulation, immunology, hematology, flow cytometry, and molecular diagnostics. Expertise and consultation are also available in all areas of "anatomic pathology", which is predominantly the laboratory testing performed on tissues, such as biopsies, cellular aspirates, and resections. At the Brown clinical sites, faculty of this department provide expert consultation in cytopathology, neuropathology, endocrine pathology, hematopathology, perinatal and pediatric pathology, gynecologic pathology, and pulmonary pathology, pediatric pathology, head and neck pathology, dermatopathology, and genitourinary pathology.
Pathologists are vital team members for diagnosis and treatment of cancer involving the breast, lung, gastrointestinal tract, head and neck, prostate, urinary tract, and female reproductive system. Our pathologists are involved in interdisciplinary clinical and translational research teams to improve diagnosis and treatment of patients with Alzheimer's and other neurodegenerative disease, cancer, diabetes and metabolic disease, perinatal and reproductive disease, adverse pregnancy outcomes, and cancer.
