Packing & Shipping Guides


  • Label each specimen with the owner's last name and the animal's name/number.
  • Clearly distinguish acute samples from convalescent samples.
  • Label serology tubes in numerical and consecutive order (1, 2, 3, etc.)


  • Place the tubes into the serum boxes in the order corresponding to the test charts.
  • Do not send specimens in hypodermic syringes.
  • Samples shipped in cardboard boxes should be placed in a waterproof liner and sealed tightly to prevent leakage.
  • If shipping fluid specimens in self-sealing plastic bags, double bag each specimen to avoid leakage.
  • Ship frozen or refrigerated material in a properly insulated container, clearly marked on the outside as a frozen/refrigerated laboratory specimen.
  • Use gel packs for a refrigerant (never use wet ice).
  • Enclose the submittal form(s) in a waterproof bag and place it on top of the specimens in the shipping container.



  • Shipping by overnight courier is preferred.
  • The sender is responsible for postage or special delivery charges
  • Please either use FedEx or UPS.  We do not recommend using the United States Postal Service for diagnostic samples.

Evening and Weekend Drop-Offs

We have staff on call to accept cases after hours. The person on call can be reached by calling 651-775-0417. The phone number is also posted at the VDL entrance. Please be aware that the on call person is not normally on site, so it is a good idea to call an hour ahead of your expected arrival time. We have added a $20 fee for accepting cases after hours to help cover these costs.
