New Genetic Test Can Detect Kidney Disease Risk in Cats

Kidney disease is common among cats, and it’s a progressive condition without a cure. Catching it early may give you the chance to work with your veterinarian to slow its progression, but even that can be a challenge, which is why experts have been working on ways to diagnose chronic kidney disease sooner. Now, there’s a new genetic test that can help you do just that. It may even give pet parents a heads-up years in advance of kidney disease symptoms.

The Feline Apoptosis Inhibitor Macrophages Test


Developed by experts at Washington State University’s College of Veterinary Medicine, the Feline Apoptosis Inhibitor Macrophages (FAIM) test is a genetic test that’s capable of helping you determine your cat’s risk of developing chronic kidney disease.  


All that’s required for the FAIM test is a swab of a kitty’s cheek, so it isn’t invasive. Once available, pet parents and veterinarians will be able to get this test in the mail from WSU’s Program in Individualized Medicine (PrIMe)—where you can also purchase a test for the MDR1 mutation, which is associated with adverse reactions to certain medications. After swabbing a cat’s cheek to get a sample, it can then be mailed back to WSU. They will use droplet digital PCR testing to look for a genetic variation that’s associated with kidney repair.   


If your cat is predisposed to the disease, you can then work with your vet to keep your pet’s kidneys healthy for as long as possible. For example, your veterinarian might recommend avoiding the use of certain medications or making changes to your cat’s diet to help maintain kidney health.


In addition to helping people determine their cats’ risk of developing kidney problems, experts hope that this test will be used by breeders to help reduce the odds of kittens being born with a predisposition to kidney disease. And the test might even help scientists find new ways of treating the condition, which is great news for cats everywhere.
