Slide Clinical Pathology The clinical pathologist at OSVS, Dr. Taryn Sibley, is board-certified by the American College of Veterinary Pathology (ACVP). Dr. Sibley works for a large commercial veterinary lab company, but her office is at OSVS. Dr. Sibley analyzes cytology slides, which are samples obtained from biopsies or body fluids, to determine the underlying disease process causing illness. Because she is in our building, she is able to analyze samples during the same day they are obtained, and provide immediate information for our doctors to use in patient treatment planning. Learn More
