Packing guidelines

Samples must be packaged using a primary container for the specimen, a secondary leak-proof container enclosing the primary container, and a rigid outer container with shipping and return address labels.  WADDL offers shippers with supplies to maintain specimen integrity and safe transportation of your diagnostic specimen to our laboratory. The shipper also meets or exceeds the safety requirements for shipping biological samples via the U.S. Postal Service and air courier (UPS and FedEx) requirements.  For ordering information, please visit WADDL Shipper.

      • Properly sealed wide-mouth, break-resistant (not glass) bottles or Whirl-Pak®
  • Label primary container
    • Label each primary containers with client name, animal name or other identifying information, and sample type (e.g., feces, uterine swab, etc.).
  • Syringes with needles attached will be discarded upon receipt

Step 2.  Secondary container
