Hi, I know this is an older post but looking for some input on a similar question/issue.
Background: My girl Zoey will be 7 in November, she has always been in good health with no major issues. I've had her since she was a puppy and had her spayed at 6 months (in hindsight we probably should have waited a little longer). We treated her for a UTI about 2 years ago, and she has been fine since. Recently I noticed she has been having incontinence issues, seeming to "leak" while sleeping and she doesn't realize that it is happening. I haven't noticed her drinking too much extra, its been a hot and humid (by New England standards) summer, so I would expect her to intake a bit more water than normal, but it hasn't seemed in excess. I feed her Holistic Select Adult Health Anchovy, Sardine & Salmon dry dog food. She is on Heartguard, we switched her flea & tick meds from Frontline topical to an oral pill Simparica in March, we also started her on Dasuquin w/MSM in March as a preventative measure to help keep her joints healthy as she ages.
Question/the point of my post: I took her to the vet this week to have her checked for a UTI due to the constant "leaking", her urinalysis came back completely normal. They also did blood work to test her kidney and liver, everything in the test came back normal, except for the IDEXX SDMA test. Per the lab results a "normal" range would be 0 - 14 μg/dL, Zoey's test came back at 15. The vet said it's nothing to be too concerned about since she is just 1 point over, and wants to have her retested in 3 months to monitor it, but of course I'm worried/paranoid! I wanted to see has anyone had any experience with this IDEXX SDMA test, has it shown up as elevated and has your dog had kidney issues? From what I've googled, it seems to be a newer test, but I'm curious how accurate is it in diagnosing kidney disease/failure.
I started her today on incontinence medicine (Diethylstilbestrol 1mg), hopefully that clears up the incontinence issue!
