Histology & Histopathology Labs

Recognized for our breadth of capabilities and professional expertise in in vivo pharmacology and biomarker discovery, WuXi Biology merges our talents in histopathology to provide an advanced support to preclinical drug discovery. We provide services in histology, toxicological pathology, and disease pathology such as oncology, inflammation, metabolic diseases and neurodegeneration with extensive and comprehensive technology and expertise and pathology evaluation. The pathology team offers a wide range of preclinical histology and pathology services spanning all aspects of paraffin and frozen slide preparation, staining, and evaluation at the designated histology labs and closely works with our clients to assure the highest quality on our histopathology studies. This combination of experience and space affords excellent capacity and throughput to meet clients’ timelines.
