Detailed Necropsy Submission Information

Bodies being submitted for necropsy should be delivered to the necropsy receiving dock on the north side of the Diagnostic Pathology Center. Submissions are accepted Monday through Friday from 8:00 am to 4:30 pm. Bodies that cannot be promptly delivered during business hours should NOT be frozen. Keep them refrigerated (~3-5°C) and submit within 24 hours. Contact us at the above number if the postmortem interval is expected to be longer than 24 hours. Small animals will be sent for cremation through PALS, Inc., and the ashes will be returned to the submitting veterinary clinic. Please do not hesitate to contact us for more information or with any questions you might have.


  • In all cases, the referring veterinarian is charged by the Diagnostic Pathology Center for the service and any associated fees. It is the referring veterinarian’s responsibility to collect payment and convey these charges to the animal owner.
  • Referring veterinarians can call (623) 806-7540 for a pricing list, quote, or further information regarding necropsy submissions.
  • Invoices are sent to the referring veterinarian after the final report has been issued.

Animal Submission Guidelines

    • Requests for necropsy will only be accepted when made by a referring veterinarian for a patient under their care. This must be the veterinarian who was treating the animal at or near the time of death.
    • Necropsies cannot be started until a completed submission form has been received.
    • We have two options for necropsy submission:
      • Electronic (preferred) OR
      • Paper
      • The paper necropsy submission form must be completed and either:
        • Emailed to
        • Faxed to (623) 806-7562
        • Submitted with the animal

Body Cooling

  • Submission of animals AS SOON AS POSSIBLE after death is critical for diagnostic success. Changes in tissues occur as soon as 20 minutes after death and accumulate over time. This is particularly true if the weather is hot, the animal was febrile (had a fever), or when disease symptoms suggest involvement of the gastrointestinal (GI) tract.
  • Animals should be refrigerated (NOT frozen) as soon as possible after death. Whole animals submitted for necropsy should not be frozen, but should be shipped delivered or shipped overnight on ice within an insulated container. When possible all remains should be refrigerated prior to shipping and should be shipped in appropriate leak proof containers with ice packs.
    Note: If circumstances prevent immediate shipping and refrigeration is unavailable, animal remains can be frozen. Frozen remains may take a long time to thaw, and greatly increase reporting time. Freezing also kills microorganisms, limiting identification, and creates serious tissue artifacts on histopathology.

Clinical History & Medical Records

The following should be included:

  • Copies of pertinent and recent medical records should be emailed, faxed or delivered with the remains.
  • A complete history providing a detailed description of the animal and documenting the duration and of signs of illness, other animals affected, other animals in the same environment, type of management, vaccinations, etc. will go far in helping us decide on the best tests to run and answer pertinent questions.
    • Note:  Lack of complete historical information does not prevent our investigation – we perform complete necropsies on all cases.
  • Notation of cases that have potential legal ramifications or insurance claims.  This does not change our investigation, but it may alter our handling of the case – we may retain samples longer, take additional photographs, etc.
  • Notation of specific questions, whether or not related to death (e.g., animal had a history of chronic lameness in the right hind leg).

Body Transport to DPC

  • Deliveries are accepted Monday – Friday (8 AM – 4:30 PM).
  • Pet owners and veterinary staff are welcome to deliver the body directly to the Diagnostic Pathology Center.

  • Animal Remains Packaging
    • Animal cannot weight more than 150 lbs.
    • Animal must be in at least one bag that is not leaking fluids.
    • Animal must then be put in a rigid outer container or cardboard box.
      • Note: Cardboard home burial boxes work well for the outer container.
    • If outside the Phoenix Metro area, the rigid outer container will need to contain ice packs around the animal remains.
      • Note: The rigid container should be plastic, waterproof, or not leak as the ice melts. Please use best judgment on selection of packaging.
      • At least one identifier should be on the animal, bag, or outer container.

Body Disposition

  • Disposition of the body should be discussed with the client by the referring veterinarian. The ONLY option available for animals following the necropsy is private or group cremation. Ashes from private cremations will be returned by courier (FedEx or other) to the referring veterinarian or agency.
  • Cremation options are limited for larger animals (>300 lbs). If cremated remains are desired for a larger animal we offer representative cremation. Please contact us with questions about this service.
  • Remains will only be released to registered pet cremation service.
  • We use PALS, Inc. for our cremation services. Visit their website or contact PALS, Inc. if you have any questions regarding the cremation process.
