Generally speaking, urinary protein is pathological and has physiological reasons. Generally, after a lot of exercise, or eating a lot of protein food, or having a fever may cause proteinuria.

Suggestion:

Generally speaking, the test results will be considered comprehensively, and should not be judged only by a plus sign of urine protein, but also by the test results of renal function, such as urea nitrogen and creatinine value. However, if the requirements of the unit are too strict, it may also affect it, or you can go to the hospital for review yourself.
