Positive urine microalbumin is not necessarily a kidney disease, but can also be seen in urinary tract infections, short-term intake of high-protein food and so on. Positive urine microalbumin does not necessarily mean that kidney disease has occurred, and small amounts of proteinuria can also occur in normal people. Patients with urinary tract infections can also develop a small amount of albuminuria. Eating a large amount of high-protein food in a short period of time will lead to an increase in the level of albumin in the blood, and the amount of protein excreted in the urine will increase, which can lead to a small amount of proteinuria. Patients with positive urinary microalbumin should pay attention to strengthen monitoring, if necessary, 24-hour urine protein measurement, renal ultrasound, renal function and other tests. Patients with suspected impaired renal function can undergo renal puncture examination if necessary to clarify whether kidney disease has occurred. Urine microalbumin positive patients, do not have to worry too much, it is recommended to timely visit the hospital, under the guidance of nephrologist, improve the relevant examination and treatment.
