I had some blood work drawn and the Dr. called yesterday to say my cholesterol was good, A1C 6.4, Red blood cells look good, something about protein in blood, the nurse couldn't tell me if it was to high or too low, but they want to do an mri of my liver to look for cirrhiosis, and are checking more blood for hepatitis, what is going on? Is there too much protein or not enough? Why are they looking at my liver?
