The Laboratory of Comparative Pathology offers the following services: Anatomic Pathology, Clinical Pathology, Histotechnology and Immunohistochemistry.
Anatomic Pathology
Complete anatomic pathologic examinations, including gross and histopathologic analyses, are performed by board-certified American College of Veterinary Pathologists (ACVP) anatomic pathologists. In addition, examination of tissue biopsies and slide evaluations are available.
Clinical Pathology
Clinical pathology services include: hematology (complete blood counts with white blood cell differentials, serum biochemical panels, hormone levels); parasitology; microbiology (bacterial and fungal identification, antimicrobial sensitivity); analysis of urine and other body fluids; serology for numerous bacterial, viral and parasitic infectious agents; and, environmental monitoring. All tests are performed by qualified laboratory professionals trained in veterinary laboratory techniques. The laboratory staff is committed to research in improved diagnostics, reference range development and state-of-the art assays. New tests are continuously being added as experimental needs change. The LCP also utilizes a network of reference laboratories to provide tests that are not performed in-house.
Histotechnology
Experienced histology technicians provide complete histology services including tissue processing, paraffin embedding, and sectioning. Routine stains such as hematoxylin & eosin, special histochemical stains, and immunohistochemistry are also performed.

Immunohistochemistry
Immunohistochemistry (IHC) allows simultaneous evaluation of protein expression and tissue morphology on histological sections. The range of applications in pathology and biomedical research is wide and includes tumor subclassification, and assessment of cell proliferation, apoptosis, angiogenesis and signal transduction.

- Unless indicate, stains are optimized and validated for formalin or paraformaldehyde fixed paraffin embedded (FFPE) mouse tissues. For staining of samples prepared differently, or from other species, please consult the laboratory before submitting samples.
- For all immunofluorescence, please consult the laboratory before submitting samples.
- For advice on sample preparation and selection of appropriate markers, please consult an LCP technician or pathologist prior to submission.
- Evaluation of IHC slides by an LCP pathologist is available; additional charges apply for this service.
