Histology Laboratory Capabilities

preclinical contract histology and pathology research and development services spanning all aspects of paraffin, frozen and plastic slide preparation, staining and evaluation.

The CBI histology laboratory offers a wide range of preclinical contract histopathology and pathology research and development services spanning all aspects of paraffin, frozen and plastic slide preparation, staining and evaluation.

Our experienced ACVP board-certified pathologists interpret slides and prepare reports, which are key to a successful histopathology study. We work closely with our clients to ensure the highest quality science on our histopathology studies.

Histology Laboratory Services:

  • All species including human, veterinary and laboratory animals
  • ACVP board-certified veterinary pathologists
  • Complete human and primate tissue bank, including a wide variety of human tumors, diseased and normal tissues
  • Devices, plastic, resin and ground sections
  • Digital image analysis, histomorphometry and photomicroscopy
  • Frozen sections, cytology and smears
  • High-quality and complete reporting, GLP
  • Immunohistochemistry, immuno-fluorescence and in situ hybridization

  • Tissue cross-reactivity studies, GLP and research


Skillful and accurate interpretation of histology and pathology specimens is critical to consistent and accurate success in efficacy, pharmacology and toxicology studies as well as understanding disease mechanisms. Only an ACVP board-certified veterinary pathologist is qualified to make these assessments on tissues from both research and GLP toxicology studies.

Our board-certified veterinary pathologists have the experience and expertise to evaluate our in-house GLP and research studies as well as our contract histopathology, toxicologic pathology and peer review studies. We provide the highest quality pathology interpretation services and report preparation as well as photomicroscopy, immunohistochemistry and histomorphometric image analysis. Our GLP and toxicology pathology reports include data acquisition using FDA Part 11 compliant pathology data acquisition systems to collect and manage pathology data, thereby ensuring the highest quality assessment and reporting of pathology data.
