Diabetic nephropathy assessment indicators are urine albumin, predicted glomerular filtration rate and some other indicators. 1. Urine albumin: It is recommended to use random urine measurement of urine albumin/creatinine ratio to reflect the amount of urinary albumin. A random urine albumin/creatinine ≥ 30 mg/g is considered increased urinary albumin excretion, i.e., albuminuria. If the urine albumin/creatinine ratio is repeated within 3 to 6 months, the diagnosis of albuminuria can be made if urinary albumin excretion increases in 2 out of 3 times and other factors such as infection are excluded. 2. Estimation of glomerular filtration rate: direct determination of glomerular filtration rate requires high equipment and has little clinical promotion value, so it is usually replaced by estimation of glomerular filtration rate. When the patient’s estimated glomerular filtration rate <60ml/min/1.73m², it can be diagnosed as a decrease in estimated glomerular filtration rate. 3. Other indicators: such as urinary α1-microglobulin, β2-microglobulin, etc., and renal ultrasound and other imaging tests when necessary. Patients with diabetic nephropathy should seek medical treatment in time to avoid delay.
