I was just at Mayo and diagnosed with stage 4 CKD. the doctors at home tried to blame the contrast for the CKD itself. It didn’t cause it but the hospital doing the test made my situation worse by not looking at my creatinine levels prior to doing the test. I didn’t know at that time how bad my kidneys were. Please check with your doctors but I was told it’s not the test it’s the contrast. There are many different types of contrast and some specifically for people with CKD. Tests can be done without contrast or there are ways to ramp up our bodies prior to a test that is critical for our health. There is contrast out there made for people with CKD.
