I have no worries regarding this, but I do have a question regarding a blood test result called the BUN Creatinine Ratio. Just to set the table, in June, 2016, I had a robotic partial nephrectomy to remove a malignant lesion on my right kidney. about 1 square inch of my kidney was removed. Prior to the surgery, my creatinine was 1.0 and my BUN was 30. So the BUN Creatinine Ratio was 30. I just had another blood test the other day and got the results. My creatinine was 0.9 and my BUN was 27, so the ratio, again, was 30.

My question is what is the significance of the ratio? And how, on this latest blood test, could I have numbers for the two compenents that were in the healthy range, yet the ratio was outside the range?

I'm more curious than concerned. The result has remained consistent over the years, and none of the doctors (priamry care, urologic oncologist and surgeon) have ever said a thing about it.
