Frequently Asked Questions
Why test with us?
Once we have determined your pet’s MDR1 genotype at WSU, veterinary pharmacologist Dr. Katrina Mealey, who discovered the MDR1 genetic mutation in dogs and cats, can work with you and your veterinarian through our online portal to determine the best course of action should your pet need to be treated with a medication known to cause adverse reactions in animals with the mutation.
MDR1 tests are run in batches on Mondays. If your test arrives in time to be included in Monday’s batch, you should receive your results on the Friday of that same week. Any test samples received after Monday morning are included in the next week’s batch.
No. The MDR1 test is specific to the MDR1 genetic mutation only. Your results will tell you if your dog or cat has the MDR1 genetic mutation.
DNA from your pet’s cheek cells using a swab is the same as DNA obtained from your pet’s blood. We offer tests using either type of sample because cheek swabs are an easy way for dog or cat owners to collect DNA samples in their own homes, while blood samples are often preferred by veterinary clinics and hospitals.
Refunds may be requested only for samples that have not been processed. All refunds must be requested within 60 days of the date of purchase. The date of purchase is defined as the day the customer’s card is charged. Please contact us at firstname.lastname@example.org to request a refund.
MDR1 genotype results are reported only to the contact on the submission form. Collective data reports generated for public distribution have no identifiable features other than breed.
Yes, we have identified many mixed breed dogs with the MDR1 mutation. Some of them do not look like herding breed dogs, so that is why we strongly recommend testing mixed breed dogs for the MDR1 mutation prior to giving your dog one of the medications known to cause adverse reactions.
