How is diabetic nephropathy diagnosed?
Your doctor will test your urine for protein. If there is protein in your urine, this could mean that your diabetes has damaged the holes in the blood vessels of your kidneys. This makes the holes big enough for protein and other nutrients your body needs to leak into your urine. Your doctor may also want to do a blood test to see how much damage has been done to the kidneys.
