Tips on Sample Collection

Tips on Sample Collection
Cheek swab

Sample cheek swabs are the easiest and least invasive means of collecting cells containing genetic material from your dog. Although it is a simple process, it is important that you fully understand how to collect a sample using a cheek swab. Follow along with us as we walk you through the swabbing process using one of our sample kits.

Each kit includes a requisition form, a return mailer, a label, and a cheek swab with a biohazard bag. After reviewing the form that came with your kit, you’re ready to start the collection process. If swabbing a puppy, it is best not to take samples from a puppy that hasn’t been weaned because some of the mother’s DNA can be present due to nursing, which can contaminate the sample. Be sure to also wait for at least an hour after the dog eats or plays with shared toys before attempting to swab; excess saliva and food particles can compromise testing and reduce the quality of a sample.

When you are ready to begin swabbing, remove the swab from its protective packaging and be careful to not let anything touch the tip of the sponge. Insert the sponge between your dog's ...

Cheek Swabs Serve a Very Important Purpose

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 ...
