The urine protein test paper is mainly used to check whether there is protein in the urine. The method is simple. Take out a piece of test paper, dip it in the urine, take it out immediately 10 to 20 minutes later, and observe whether there is blue. Generally, the negative is light yellow, while the positive is blue. The darker the color, the higher the urine protein. However, this inspection method is not very accurate, so it is recommended to go to the hospital for inspection when necessary. Generally, the more urinary protein content is, the worse the filtration function of the kidney is. Urinary protein is an important indicator to measure renal function.
