Samples may be submitted to our laboratory to be tested for Chronic Wasting Disease (CWD) or Bovine Spongiform Encephalopathy (BSE). Acceptable samples include either whole carcasses or heads, or brain with brainstem if removed and properly preserved by a veterinarian or certified CWD technician.

Currently there is no charge for BSE testing, however extraction fees, necropsy fees, and/or disposal fees may apply.

Because it is a regulatory disease, all samples submitted for CWD testing MUST be accompanied by completed CWD testing submission forms and chain of custody forms.

Hunters may have harvested deer tested for CWD. The fee for this test if entire head is submitted is $80. The hunter may deliver an entire head or may contact a veterinarian or certified CWD technician to remove, properly preserve, and submit the brain stem and lymph nodes from the head. No part of any samples submitted to the laboratory may be returned. See FAQs for testing of hunter killed deer. Certified CWD technicians can by located by contacting your PA Department of Agriculture regional office.

As of January 1, 2012, USDA has discontinued funding for CWD testing of farmed deer. Therefore, CWD testing will no longer be free of charge. Charges for CWD testing will now be $25, with additional fees for sample collection and disposal when applicable. See this document for a further explanation of new CWD fees.

These analyses are not performed at the PSU Animal Diagnostic Laboratory, but are shipped to outside laboratories for testing. Approximate turn-around time for BSE testing is 3-5 business days and for CWD testing is 6-8 weeks depending on the current volume of sample submission.
