Non Human Exposure Rabies Submisson Form

A completed rabies submission form MUST accompany each submission. Contact with suspect carcasses and samples should be avoided if possible. If some contact is necessary, gloves should be worn.

Rabies testing for livestock and non-human exposure cases is performed at the Pennsylvania Veterinary Laboratory (PVL) in Harrisburg, see this webpage for more information:

Acceptable specimens

No live animals will be accepted for rabies testing at the Animal Diagnostic Lab.

The Department of Health Rabies lab may accept live bats.  Please see the DOH website for more information.

If the animal is alive;

  • Livestock and companion animals - contact your local veterinarian for euthanasia
  • Wildlife - contact your local PA Game Commission field officer for capture and euthanasia (PGC Contact Page)
  • Stray or feral animals - contact your local animal control officer for capture and euthanasia

To ensure accurate testing results, care must be taken to avoid injury to the head and/or brain of suspect animals.

Carcasses, heads or whole brains are acceptable submissions for rabies testing at ADL. Bats should always be submitted intact for identification purposes. Specimens should be refrigerated (not frozen) as soon as possible after death. If further diagnostic work is to follow a negative rabies test, the laboratory must be informed at the time of submission, to ensure that proper tissues are saved. For safety purposes, no additional tests are performed on specimens after a positive rabies test is received. No part of any animal submitted for rabies testing will be returned, regardless of test results.

How to submit specimens for rabies testing

Hand delivery of specimens for rabies testing is recommended when possible. Facilities are available for submitting specimens after hours (weekends or evenings) for processing on the next business day. If hand delivery is not possible, samples may be shipped. Please see shipping guidelines for further information.

Samples that are dropped off at the Animal Diagnostic Lab at University Park PA will be shipped by overnight courier to Lionville PA. Samples will only be shipped on weekdays Monday through Thursday as the Department of Health no longer accepts routine rabies specimens for Saturday delivery. Samples dropped off in the overnight drop off area will be shipped on the next business day.


Results can be expected 24-72 hours after sample is received at the lab in Lionville, PA.

The result of rabies testing on the brain is provided to the veterinarian and/or physician associated with the case. If the test is positive, the Bureau of Animal Health and Diagnostic Services and the Department of Health are also notified. Quarantine of animals, if necessary, is administered by PDA Regional offices. Please contact your regional PDA office with any questions regarding rabies quarantine.
