Pregnancy, being in heat, and medications should not alter the test results.
If a medication causes your dog to have a dry mouth, you will want to take a little bit longer to swab to be sure sufficient saliva is collected.
Dogs with oral cancer or cancer affecting the lymph nodes or salivary glands may end up with poor quality genotyping if the sample includes cancer cells. If your dog has a growth or tumor in his or her mouth, we recommend swabbing on the other side of the mouth.
What if the analysis fails?
If for some reason, we are unable to use the sample you've provided, we will notify you right away and send free replacement.
