Research Services

At the Comparative Pathology Laboratory, we have a wide range of staff with the expertise to assist you with your research project. We offer the following services:

  • Necropsy of study animals, gross dissection of target tissues, and photo documentation.
  • Histopathological tissue processing and interpretation by board-certified veterinary pathologists with semi-quantitative data collection and photomicroscopy, as needed.
  • Collection of peripheral specimens during necropsy for serology, clinical pathology, parasitology, microbiology, and/or PCR and subsequent processing of collected specimens.
  • Consultation on experimental design and sample collection.
  • Figure and text generation for publication.
