About COVID-19 Testing at Penn's Veterinary Diagnostic Laboratory

The PennVet Diagnostic Lab will not be testing the general companion animal population for the SARS-CoV-2 virus.
According to the United States Department of Agriculture (USDA), the testing of companion animals is not recommended. Testing may be done by animal and public health officials if they agree that there is a link to a known human case. If you have such a case, please contact your state animal health official. In Pennsylvania, please call the Pennsylvania Department of Agriculture at 717-787-4737 and ask to speak to someone about testing an animal for SARS-CoV-2.
