What does urine protein positivity mean?

Urine protein positive we see more clinically when doing physical examination, or when patients go to the hospital to do urine tests, found that urine protein positive is a plus or two plus signs, this time must be treated differently. Normal urine protein can be added, or occasionally a plus sign, this is a normal phenomenon. If there is no other discomfort, other urine tests are normal, that is, pure urine protein, trace urine protein does not need to be processed, you need regular review can, perhaps the next time you re-test urine protein is already normal. If the amount of urine protein is relatively high, two or three plus signs or four plus signs, be sure to go to the hospital to find out what is the cause of urine protein, urine protein is the most common cause of kidney function damage. For example, glomerulonephritis, nephrotic syndrome, renal arteriosclerosis, etc., will show more urine protein in the urine.
