Urine microalbumin 80mg/L is not normal, under normal circumstances the kidneys are mildly permeable to albumin, the kidneys are able to lose a small amount of albumin, usually at a concentration of 30mg/L or less. If between 30mg/L-300mg/L is called microalbuminuria, and more than 300mg/L is called macroalbuminuria, which shows that urinary microalbumin 80mg/L belongs to microalbuminuria. There is a difference between urinary microalbumin and urinary protein in routine urination, if urinary protein is found in routine urination, it means the disease has appeared for a long time; while urinary microalbumin is to screen for early kidney disease, especially diabetic nephropathy. Urine microalbumin appears earlier than urine protein, which can detect kidney disease early and intervene early for treatment, which is helpful to stop further deterioration of kidney function. Elevated urine microalbumin is usually treated with valsartan capsules or Benadryl tablets.
