WebJul 1, 2024 · DM is diagnosed presumptively through genetic testing. Blood or a cheek swab is sent to the lab and evaluated for the genetic marker. There are three possible test results: N/N – both copies of the gene are normal, and the dog does not have DM. N/A – the dog has one normal copy of the gene and one abnormal/affected copy of the gene.
