12/23/20: Price increases for necropsy cases for non-food animals.
We will be increasing the prices for necropsy cases for companion animals beginning January 11, 2021. The VDL has increased prices on food animal case submissions over the past two years to more closely reflect the costs of providing the diagnostic services, and now we are doing the same for the non-food animal cases. We continue to work on measures to reduce costs to ensure we can sustain our ability to provide high quality service. Please contact Dr. Jerry Torrison if you have any questions or concerns regarding these changes.
