No it is not the latest Calvin Klein scent, it is Chronic Kidney Disease.
I have been diagnosed with CKD, but it is one of those things that you may have as well. There are 5 stages to CKD. My doctor tells me that I am at Stage 2. He said that is what the government would tell you. I am not so sure that he agrees with the rating system. Lots of people are running around with Stage 1 and Stage 2 without any symptoms.
I was not experiencing any symptoms, but per other blood tests, it was determined that I should have it checked out.
I have had several blood test and my creatinine levels have consistently be elevated, hence I have CKD.
I have also had an ultrasound and MRA, which has determined that the blood vessels in one of my kidneys is smaller than the other.
