In submitting samples to the laboratory it is important to package it correctly. In general, the specimen should be enclosed in its firmly sealed container in a sealed polythene bag containing vermiculite or other absorbent material. It should be placed in a strong cardboard box and submitted in a padded envelope. A submission form with the animalís details and a description of the lesion should be placed in a separate polythene bag within the package to prevent any leakage interfering with the writing. It may be helpful to read the regulations for sending pathological specimens through the post.
