24-hour urine protein quantitative 200mg may be due to improper diet, stress and other physiological factors, or due to glomerulonephritis, diabetic nephropathy and other diseases. Under normal circumstances, 24-hour urine protein quantitative should be less than or equal to 150mg, so 200mg beyond the normal range, consider proteinuria.
