Cheek Swabs Serve a Very Important Purpose

Canine genetic testing is somewhat of a mystery for non-scientists who are just starting to learn more about the ins and outs of the genetic world. I was recently given the opportunity to tour Paw Print Genetics’ state of the art laboratory and was amazed at what is possible to achieve with the sample after the simple act of swabbing a dog’s cheek.

During the tour, it dawned on me that one of the most important parts of the process of genetic testing is the moment when the cheek cells are being collected. Although the process itself is not complicated, it is still important to make sure to collect as many cells as possible and avoid collecting foreign matter that might interfere with the testing or confound the results. The cells that are being collected are dead skin cells, comparable to how we shed skin from our arms. It is a painless process for the dog but  might make them a little uncomfortable so having a friend help  collect the cells would be a good idea.

Optimal collection of cells  is achieved when the inner cheek surface is brushed for a slow count of 30 using the cyto-brushes provided by ...
