Microalbumin and protein belong to two indicators, usually belong to the results of urine examination, considering and physiological factors, specimen contamination, kidney disease and other factors. 1. Normal microalbumin: microalbumin is a trace amount of albumin in human urine, under physiological conditions, only a small amount of albumin will appear in urine, which can be used to monitor the occurrence of kidney disease, if the result is normal, there is no need to worry and no need for special treatment. 2. High protein (1) Physiological factors: some patients may have transient high protein symptoms due to strenuous exercise, excessive intake of food with high protein content, etc. Usually, no special treatment is needed and it can be relieved quickly. (2) Specimen contamination: high protein in urine may also be related to the patient’s lack of standardization in retaining the specimen, which may be affected by secretions or external environment, thus resulting in a false-positive state, which can be reviewed and treated. (3) Kidney disease: If the patient has kidney injury, the glomerular basement membrane will be damaged, which will change the permeability of the basement membrane, and then the urine protein is high, accompanied by abdominal pain, fever and other symptoms. Patients can go to the hospital, cooperate with the doctor to improve the relevant examination, understand the specific causes and then follow the doctor’s instructions for treatment.
