Genetics Testing

Recent advances in molecular genetics provide the groundwork for the development of genetic tests for the diagnosis and prevention of inherited diseases. As a result of this progress, genetics will become an integral part of veterinary medicine. Veterinarians will be able to accurately diagnose inherited diseases and detect carriers to help breeders make breeding decisions. DNA tests are safe, easy to perform, and reliable if interpreted correctly. Genetic tests only need to be performed once in an animal's lifetime since results of DNA testing never change.

DNA can be isolated from any cell in the body except red blood cells. Most genetic testing can be run using DNA isolated from buccal mucosal swabs of the animal's mouth. This is a non-invasive procedure and can be done by the owner. Buccal swabs can be taken at any age; however, young animals should be weaned to avoid the mother's white blood cells from milk giving false data.


The buccal swabs, which are 6 inch sterile cytology brushes, can be obtained from companies that perform DNA testing. The swab is gently rubbed with a back and forth motion on the buccal surface of the mouth and then placed in a sealed envelope prior to mailing to the company. Swabs are available free of charge by companies performing the tests. Some genetic testing companies require whole blood, which is collected into EDTA tubes and should be refrigerated.
