Be sure to use shipping containers that seal tightly, provide proper temperature requirements for the particular specimen, and send as quickly as possible. Clearly identify each sample with the animals ID, owner's name, and veterinarian or practice involved. A full history is always helpful to assist us in providing the best possible diagnosis.
