Biopsy & Histopathology Service

This section provides diagnostic service for evaluation of biopsy specimens from live animals as well as histopathology analysis of tissues sent in from field necropsies. This may include submissions for histopathology in conjunction with Bacteriology, Virology, Parasitology, and/or Toxicology and include interpretation of the results by the coordinating pathologist or case coordinator. The histopathology laboratory processes samples for the Diagnostic Laboratory as well as for research needs for the college. A wide variety of special stains, including immunohistochemical staining are available. View our Histology Stain and IHC list for more information. Packaging Samples Package fresh tissues in inner leak-proof containers such as Whirlpaks. Surround these with enough absorbent material to soak up any spills and ship in a leak-proof, well-insulated outer container. Include several ice packs to keep the tissues cold until their arrival at our laboratory. Make sure samples are properly identified. Package formalin fixed tissue in leak-proof containers surrounded by absorbent material. This is especially important for our continued service because of concern and Department of Transportation regulations regarding shipment of and exposure to chemicals such as formalin. In addition to public safety, fresh tissue accidentally exposed to formalin is non-diagnostic for many laboratory procedures, this includes cytology slides; cytology specimens should never be included in packages containing fixed tissues. Parafilm insures against leakage on most containers. If time is allowed for tissue to fix properly before mailing, only a small amount of formalin needs to be shipped with the sample. Label individual tissue containers with veterinarian, owner, animal ID and type of specimen. Please do not use narrow necked containers as it is very difficult to remove fixed tissue from them. We supply fixative filled jars in pre-paid mailers for your convenience.

Getting Results

Tissue specimens arriving at the laboratory by 3 p.m. are processed overnight and slides are ready for interpretation by the pathologist on duty after 12:00 p.m. the following day. Preliminary biopsy results are available usually within 24 hours. If you need results as soon as possible, please do not hesitate to call. Cases with ancillary testing (microbiology/toxicology, and others) take longer but preliminary histopathology results are available within 24 to 48 hours. Consultation with the original pathologist is always available as is review of difficult cases by a second pathologist.
