Welcome to you and your two new babies
I know how you feel about kidney function tests , having also lost my previous dog to the horrible disease. I never want to see a pet so very sick, and die so suddenly after diagnosis. I had no idea my baby was sick and a minor tummy upset revealed the horrible truth! So this SDMA test seemed very important to me if it would allow a diagnosis long before the 75% function loss was apparent.
I am so sorry that the test did show the possibility of early kidney disease in your boy, so young! It is great that all the other tests were normal.
I wonder if this Test has been in the field for such a short time that it may need more statistics on the numbers? I would like to know how the numbers change with age for instance? I am sure the research is ongoing and hopefully we will learn more about the limits of the test ranges and their reliability and accuracy.
Praying your boy responds well to the care regimen and that the kidney function remains good. Looking forward to your updates.
