High microalbumin 24 hours quantitative normal may be physiological factors (such as strenuous exercise) or pathological factors (such as early diabetic nephropathy), need to be specifically analyzed. 1. Physiological factors: some people will have elevated urinary microalbumin after strenuous activities, but the 24-hour urine protein quantification is normal, usually without other discomforts, and it can be restored to normal after sufficient rest. 2. Pathological factors: some diseases can appear in the early stage of urinary microalbumin elevation, such as diabetic nephropathy in the early stage, there can be persistent microalbuminuria, but the 24-hour urine protein quantitative can be normal, to be progressed to the stage of diabetic nephropathy, there will be a large amount of albuminuria, renal puncture biopsy and other tests can be used to assist in a definitive diagnosis. If the urine microalbumin is elevated, it is recommended to consult a doctor in time, except for pathological factors, to avoid delaying the condition.
