@m1miller Most nephrologists will tell us an eGFR of 30 is where we start questioning the use of contrast. Low dose or no contrast at that point, whenever possible.

@ajnos Our kidneys clear contrast material out of our system. As our kidney function declines, we want to avoid stressing them and possible causing more issues. I recently had a knee ablation, and they used a small amount of contrast to "light up" just where they were injecting things. I agreed to it because I am already on dialysis daily.

@tinabear26 Welcome to Mayo Clinic Connect! You have had some good responses already, here! Looking back, have you had an infection recently? New medication that might have this side effect? Dehydration issues? Different processing lab? It must be concerning for you to see this! How are you feeling today?
