uacr refers to urine albumin creatinine ratio, which can monitor the urinary protein excretion, and its normal value is about 30mg/g or less. uacr is the medical abbreviation for urine albumin creatinine ratio, known as urine protein/creatinine ratio measurement, is an important indicator to determine the degree of kidney damage in the early stages of diabetes, hypertension, hyperemesis gravidarum and other diseases. It is understood that this indicator is related to 24-hour urine protein, which not only can accurately predict 24h urine protein excretion, but also has the advantages of rapidity, accuracy as well as simplicity compared with the traditional 24-hour urine protein quantitative indicators. In general, the normal value of uacr is about 30mg/g or less. If the actual value is between 30~300mg/g, then it belongs to the microalbuminuria stage, which indicates that there may be early kidney disease. And if the actual indicator is more than 300mg/g, then it means that the body contains a large amount of proteinuria. Once the uacr value is found to be more than normal, then further examination should be carried out in time to detect the disease as early as possible and actively cooperate with the doctor’s treatment to avoid aggravation of the condition.
