Sampling Protocol for PVL:

Referring veterinarian must first complete COVID-19 Veterinary Worksheet ( and receive confirmation from PDA/DOH testing authorization is approved.
Licensed veterinarian:

  • Submit a nasal swab (preferred) and oropharyngeal (or oral) swab in 1-3 mL of Brain Heart Infusion (BHI) broth or Viral Transport Medium (VTM). It is acceptable to discard approximately half of the BHI if provided with 5.5 mL tubes of BHI to obtain the proper amount of BHI broth in the tube. Rectal swab/feces can also be submitted but are not preferred specimens.
  • Use synthetic (dacron or rayon) tipped, plastic shaft swabs. Do NOT use calcium-alginate, cotton tipped or wooden shaft swabs.
  • Ship specimens overnight on iced gel pack along with a completed General PADLS submission form, available at Freeze specimens prior to shipping if they will not reach the lab within 48 hours of collection. Clearly write: “Prior Authorization-19” on box/label.
  • Testing fee at PVL is currently $50/specimen unless waived with prior authorization.

Samples may be shipped by the licensed veterinarian using whatever overnight shipment or courier service they prefer to get them to the Pennsylvania Veterinary Lab (2305 N. Cameron St. Harrisburg, PA 17110). Do not use priority mail.

If veterinarians send samples with a request for SARS-CoV-2 testing to private labs without prior approval by PDA/DOH, that lab should call PDA and/or DOH for permission to test before testing those samples.
