Remy came back from the vet after being spayed. Before the surgery they did a blood screen to check kidney, liver and other levels. They said the normal kidney value is 1.4 and Remy's was 1.9. The vet tech said the Dr. wasn't too concerned and went ahead with the surgery, but we have to have the levels re-checked next month. I tried to ask what this meant and the tech kept repeating that I should have her tested again in a month to see if it goes down. What does an elevated kidney level mean? How serious is it? Should I be out of my mind with worry? And why would the level go down? As far as I know Remy does not exhibit any abnormal symptoms that would relate to kidney issues.
