General Supplies Needed to Ship Specimens:

  • Use the most current diagnostic lab submission form, which can be found on our Submission Forms/Fees page.
  • Leak-proof container non-permeable to the contents. Recommend use of Parafilm Wrap to seal lids
  • Absorbent material sufficient to soak up liquid contents in case of leakage
  • Cold Packs (no ice cubes)
  • Sealed inner container
  • Sealed plastic bag containing submission forms/documents; placed outside the inner container.
  • Outer container such as a Styrofoam-lined box, cardboard box, etc.

Shipping Procedures:

  1. Shipping guidelines and requirements for shipment of biological materials may be provided by the shipping service company (USPS, FedEx, UPS, etc.)
  2. Weekend Delivery/Sample Integrity: Please note that weekend & holiday deliveries are not possible due to unavailability of receiving personnel. Packages should be shipped so that they arrive no later than 2:30p.m. Monday through Friday. Samples should be submitted in the most timely manner possible to prevent deterioration and ensure diagnostic integrity.
  3. Sample Identification: Label all samples, including the animal’s name or identifying number, owner’s full name and sample source & sample type.
  4. Submission Forms/Documents:  Include completed submission forms inside of a separate Ziploc-type bag to prevent damage from fluid-containing sample leaks. Incomplete submission forms may cause a delay in accessioning of the samples. Please use the submission forms found here:
  5. Fluid-containing Samples: Use a leak-proof container and place sample inside a sealable specimen bag (Ziploc) with absorbent material such as paper towels. Use parafilm sealing tape around the lid/tops of the containers to prevent leakage.
  6. Ambient Samples: No ice packs necessary for shipping.
  7. Refrigerated Samples: Do not ship samples with ice cubes as they will melt and leak out. Use commercial grade frozen ice packs. We recommend the use of a Styrofoam cooler box inside a cardboard box.
  8. Frozen Samples: Ship on dry ice or if allowable, ship on sufficient amount of ice packs to keep sample viable. No ice cubes.
    When shipping frozen samples on dry ice and non-frozen samples such as formalin-fixed samples together, package samples separately so non-frozen/fixed samples are kept safe from freezing. Suggestion: Use of a second insulated container within primary shipping box or wrap non-frozen samples with insulating-like material.
  9. Protection: To prevent breakage, pad the samples with bubble wrap, newspaper or some similar type of packing material.
