Creatinine and diabetes are linked but good care can makes a difference. Creatinine is a waste product found in a blood sample and an eGER test of this will show how well the kidneys are working. Therefore ask the doctor if you need this once a year along with A1C level twice a year, and blood pressure. Find out from him whether it will be good for you to take an ACE inhibitor or ARB and have the amount of protein in your urine measured at least once a year. Work also with the health care provider about meal planning especially if you have to reduce the protein intake, exercise, monitoring the blood sugar, medicines and insulin injections.
