The SDMA Test – Dog And Cat Owner Feedback & Comments

Back To The Main SDMA Article

Let other readers know about your pet’s experience with the SDMA kidney test  

What is your pet’s name? Where do you live? How old is your pet? Were the SDMA test results consistent? Did SDMA levels go up before creatinine levels went up? What were its creatinine levels? Were other laboratory or urine tests abnormal? Was your pet ill at the time of the test? When that illness passed, did the pet’s SDMA levels go down? Was a special diet recommended? Did SDMA levels return to normal on the new diet? Would your dog or cat eat it? Did the pet’s weight on the new diet change? What medications were recommended? Anything else you would like to add?

We have an 8-yr-old golden retriever who has been very healthy her entire life. I agreed to have our vet do preventative screening bloodwork on her during her last vet appt. Her SDMA was slightly elevated (17). No other numbers were out of range in her blood or urine. Six weeks later we had it checked again. The SDMA # remained slightly elevated (19). Everything else was normal. Our vet wants me to put her on renal Diet RX food. I don’t intend to do so at this juncture.  Even if she does have early stage CKD, it seems it must be very early and the RX diet would likely do more harm than good by scaling back too much on protein. I am going to be cognizant regarding not give her any treats that are high in phosphorous. Our dog gets EXTREMELY STRESSED when we go to the vet or groomer. Could that account for her elevated SDMA level? At the moment, I am on the fence about repeating her bloodwork in another few months, or just waiting a full year.

Strenuous exercise is known to elevate kidney-health markers such as creatinine in humans. (read here  and here ) No one knows if it elevates SDMA as well because human nephrologist do not believe that the SDMA kidney test is worth running.

My cat’s name is Hakeem. He is 5 years old and eats Dr. Pierson’s raw food recipe. His case puzzles our vet. Hakeem’s SDMA test is in the normal range but his creatinine is 2.1 ( Antech 0.6-2.4) and his BUN is 28 ( Antech 14-36). His creatinine and BUN are logically elevated since he eats NO carbs. IDEXX says that 4% of the cats have this low SDMA combined with high creatinine, which they cannot explain. So, this test will not be reliable for us. I am VERY confused our vet discarded the SDMA results altogether. This puzzle is not discussed very much on the Internet. It would seem vets, and vets at Idexx too, are so unfamiliar with cats that don’t eat carb-stuffed kibble, that they are biased in their analysis. Cheers from Delphine, Hakeem, and younger brother Mehdi and thank you for your interest in my black, Caribbean panther… Enjoy your evening!

You asked about SDMA levels in chronic kidney disease in cats and how they change over time. My cat Penney was diagnosed with CKD in early 2018.  [ ]  She is still doing well and has not lost any weight since her diagnosis. Her blood phosphorus still very low at 3.6 on her last test without using a phosphate binder.  She is now about 14.5 years old and my vet says she still has excellent muscle.
Here are her Creatinine and SDMA values:  

Her SDMA has really bounced around.  I’ve read your articles and do wonder how useful it is as an indicator of her CKD progression. Hope this helps!

Hi Ron,

My 17 year old Boston’s kidney values suddenly went through the roof. Creatinine 1.1 to 3.9, BUN 33 to 134, Phosphorus 4.7 to 11.2 . Oddly, her SDMA went down, from 10 to 8. This may be due to the things I have been giving her that have been shown in studies to be nephro-protective when the kidneys are damaged in various ways:  Berberine (a lot of rats died proving this) and milk thistle combo, L-carnitine, krill oil for omega 3s, fisetin, and pyridoxal 5 phosphate.  She also had a triple strength IV stem cell injection (VetStem) a couple of months ago. Two questions for you:

How reliable is the SDMA when it goes down? Is there enough phosphorus in pyridoxal 5 phosphate to cause trouble?  It is thought to be great for kidneys. Forgot to mention I give Licorice lots of curcumin (Theracurmin).  There have been a number of studies about curcumin preventing kidney damage.

Thanks, Rob.S., Riverside, CA

Hello Dr Hines

Our dog’s name is Nyawela Busveld Lehabah. We live in France on the Swiss/German border. Our dog is a 2-years-old Rhodesian Ridgeback. I breed them. I feed them a raw meat diet. An ultrasound of our dog’s kidneys showed one smaller than the other. Our dog’s SDMA level went up when his creatine level was only 1.1 mg/dl. His urinalysis was normal and he showed no signs of illness. Our veterinarian recommended Royal Canine Renal Support diet. Along with an additional 100 mg/kg of additional water throughout the day. When we switched to this diet, his SDMA levels went back down to 9. We added taurine to the diet on the advice of our veterinarian. Now the dog’s SDMA level is back up to 16/mg/dl. I wonder if the SDMA level is a valid gauge of kidney function or if the taurine supplement made the SDMA values go up.
