Pathology Services

Pharmaron provides a wide array of routine and specialized toxicologic pathology services to help our partners determine the safety and efficacy, and investigate the potential mechanisms of test articles by which changes are induced. Pharmaron’s pathology team performs pathologic assessments and provides interpretations that meet the requirements of multi-GLP compliance of US FDA, OECD and NMPA.

Pharmaron’s contracted US Board Certified Veterinary pathologists and China board-certified pathologists provide thorough interpretation of pathology data and comprehensive report preparation that includes data acquired by using FDA Part 11 compliant pathology data acquisition systems of Provantis.
