Urine microalbumin/urine creatinine should normally be less than 30 mg/g. A high ratio usually suggests kidney damage and can be used to screen for early nephropathic disease. Kidney damage may be related to glomerulopathy, tubulopathy and other factors. 1. Glomerulopathy: It includes kidney diseases such as nephrotic syndrome, glomerulonephritis, etc. After kidney damage, albumin cannot be filtered, resulting in albumin being excreted in urine, which leads to high urinary microalbumin/urine creatinine. 2. Renal tubular disease: including diabetic nephropathy, hypertensive nephropathy, acute interstitial nephritis and other diseases, mainly because the renal tubules can reabsorb albumin, when the renal tubular disease, albumin can’t be absorbed, which causes high urinary microalbumin/urine creatinine. If the urine microalbumin/urine creatinine is abnormal, you should go to the hospital in time, to clarify the cause of the disease, and follow the doctor’s instructions for symptomatic treatment in time.
