Urine protein (++) in most cases indicates that the patient has nephritis. Under normal circumstances, urine protein in urine is negative, while some people may exercise strenuously or have a fever before the urine test, which may result in a positive urine protein in the urine routine, but the amount is relatively small, usually (±) or (+), and will not exceed (++). If it is (++), the amount of urine protein is more, which in most cases suggests possible nephritis, the most common being chronic nephritis. Relevant tests should also be improved to rule out the possibility of secondary nephritis, such as lupus nephritis, purpura nephritis, etc. Urine protein loss from the kidneys can also damage the kidneys, so once urine protein (++) is found, it is recommended to perform 24-hour urine protein quantitative examination, if more than 1g or more, it is necessary to use some drugs to reduce the amount of urine protein, such as valsartan or benazepril, the Chinese medicine Huangkui capsule is also more effective in reducing urine protein, and if necessary, hormones can be used to treat.
