Urine microalbumin 32mg/L is not normal. The normal value of urine microalbumin is 30mg/L. Urine microalbumin 32mg/L, which is slightly higher than the normal value, indicates that there are trace amounts of albumin in the urine, but it is not serious. Slightly high urine microalbumin may be caused by physiological factors, such as strenuous exercise, high protein diet, etc. It may also be caused by pathological factors, such as hypertension, diabetic nephropathy or other early stage of nephropathy, kidney injury and so on. If the examination found that the urine microalbumin is slightly higher than the normal value, you can take a rest and review, and at the same time improve the renal function, urine routine, urinary tract ultrasound and other examinations. It is recommended that patients with abnormal urinary albumin should go to the hospital in time to improve the relevant examinations under the guidance of the doctor, and if it is caused by pathological factors, it should be actively treated to avoid the development of the disease.
