The results of the function of the kidney function is normal! Glycated 4.6, microegg fraction 2, 22mg Is it diabetic nephropathy? Gao Hailin: Please give the microalbuminuria is 2.22mg/dl, or 2.22mg/min?One abnormality cannot diagnose diabetic nephropathy. It should be checked several times, and it is better to check the microalbumin of 8-hour urine. A retinal examination of the fundus should also be done. From your letter, it seems that the blood sugar is well controlled, but I wonder how is the blood pressure? How many years have you had diabetes? Blood pressure and blood sugar are the key aspects of not having diabetic nephropathy. Patient: Thank you, Dr. Gao.
