You will need this registration if you intend to operate a veterinary diagnostic laboratory.
A veterinary diagnostic laboratory is a place in which samples or specimens from livestock or livestock products are tested or analysed for the purposes of determining whether they are affected with a disease or contaminant. However, this does not include a place or business of a veterinary surgeon if the only samples or specimens that are tested or analysed come from livestock being treated by a veterinary surgeon in the ordinary course of their practice.
