Welcome to PennGen Laboratories


New: Genetic Testing Update

We are happy to announce that the PennGen Laboratories are now offering genetic testing for Microphthalmia and Degenerative Myelopathy in Soft Coated Wheaten Terriers (and can use DNA samples already in our lab from previous PLN testing)” Click on (link to the announcement document) for specific instructions and costs.

Hereditary diseases of companion animals are an important problem for clinicians, breeders and owners. More than 900 inherited disorders have been identified in the dog and over 200 in the cat. The Section of Medical Genetics at the University of Pennsylvania's School of Veterinary Medicine has been in the forefront of reporting and characterizing hereditary diseases in companion animals for more than 40 years, including research to uncover the genetic basis and developing genetic tests for canine and feline diseases. PennGen is a genetic testing facility operated through the Section of Medical Genetics as a collection of not-for-profit laboratories offering testing for a variety of genetic diseases, metabolic screening for inborn errors of metabolism, hematological, and other diagnostic services.

COVID-19 Update

April 28, 2020 -- Due to the ongoing COVID-19 emergency, the PennGen Laboratories have instituted safe distancing practices and are still processing Metabolic and DNA tests, as they have diagnostic ramifications for your pet.

  • Included Tests

    We will continue to preserve all samples received, so that previously untested samples can be successfully processed as we resume our normal laboratory activities. We remind you that for DNA testing, blood samples (collected in purple top tubes) are much more reliable and durable than cheek brush samples.

    We are of course sorry for the inevitable delays in processing your submissions due to protocols we have instituted to keep ourselves healthy and able to continue to work. We appreciate our University’s concern for our health and safety, and hope you are able to protect your health as well.   Thank-you in advance for your patience and understanding.
