For Veterinarians

We want to make MDR1 testing for your feline and canine patients as easy as possible. Please contact us about billing options we offer to veterinary clinics and hospitals. $70 (US) for test.

Sample submissions

We accept blood and DNA collection brush samples from veterinary clinics and hospitals.

To submit a sample for MDR1 testing, please fill out the submission form. You will receive an order confirmation with a sample identification number. Please print one copy of the confirmation for your records and include one copy with your shipment.

If you are a clinic or hospital and need to make a bulk order of DNA collection brushes, please contact us.

When you test with us, you will have access to MDR1Caddie™ to consult with veterinary pharmacologist Katrina Mealey, DVM, PhD, DACVIM, DACVCP, who discovered the MDR1 genetic mutation in dogs and cats. She can work with you to determine the best course of action for your patients who need to be treated with a P-glycoprotein substrate drug.

Dr. Mealey is the founding director of the Program in Individualized Medicine at WSU and is recognized as a global expert in veterinary pharmacogenetics.
