Animal Diagnostic Lab (PSU) Mammalian Necropsy Services

We’re excited to announce that effective immediately, the Animal Diagnostic Lab (PSU) is accepting mammalian necropsy cases. Our new mammalian pathologist, Dane Rahoi, DVM, Dipl. ACVP, is eager to work with you to solve disease situations you and your clients are facing.

We’re still working on hiring a second pathologist to work alongside Dr. Rahoi, so there may be an occasional time when our response time might be slightly delayed. Please feel free to call with any questions or concerns! ADL Main office - (814) 863-0837; Dr. Rahoi - (814) 865-3728; Dr. Hovingh - (814) 863-3745

There is no longer a need to call ahead to submit a case to the lab. Outside of regular hours and on weekends, carcasses may once again be left in the necropsy cooler. Please make sure the appropriate paperwork is completed. And just a reminder that on “home game” weekends it can be a significant challenge, if not impossible, to get to the ADL, so plan accordingly if your clients need to drop off a carcass those weekends.

PA Veterinary Lab

Beginning on June 20, 2023, the Pennsylvania Veterinary Laboratory in Harrisburg (PVL) is adjusting its avian specimen drop-off time to be 10:30 am for same-day testing results, subject to change as needed. This change does not affect the drop-off times at Penn State's Animal Diagnostic Lab or New Bolton Center.

Manheim Field Office: The Manheim Field Office is scheduled to reopen for submission of swabs, blood, and other similar sample types ONLY on Monday May 8, 2023. Birds should NOT be submitted through the Field Office until further notice.

SARS CoV-2 Sampling Protocol for PVL:

With continued evolving situation, preauthorization for SARS-CoV-2 testing of animals is no longer required but the specimen must be submitted through a veterinary clinic following our collection and shipping guidelines. Please call the lab to discuss submission @717-787-8808

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. Swabs submitted in collection media with gel are not acceptable.
  • Package specimens as directed by IATA shipping guidelines as for any other diagnostic specimen. Ship specimens overnight on iced gel pack 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.
  • 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.

With the current mail and postal issues, we are encouraging adoption of electronic submissions for EIA testing. PVL now offers a total of 4 different Coggins submission/reporting methods and 3 of them are electronic:

  1. VS Form 10-11 (dated FEB 2018 or later) - hardcopy results are currently mailed via USPS
  2. PALIMS Mobile App - along with the PADLS Online Portal, this electronic option provides faster access to results – No Fees
  3. GlobalVetLink - web-based electronic system; fast access to results- Fee-based service
  4. VSPS - USDA's web-based electronic system; fast access to results - No Fees USDA APHIS | Veterinary Services Process Streamlining (VSPS)

With current postal delays, we are temporarily advising, especially for “urgent” or “rush” cases, that those samples where possible are either hand delivered or sent via an overnight courier service with a guaranteed sample delivery at the laboratory.
