Urine protein negative. What do you mean?

Urine protein is a normal component of urine. Under normal circumstances, the content of urine protein in urine will not exceed 150mg within 24 hours. The test results in urine routine examination generally show negative. If it exceeds this normal range, it generally indicates that urine protein is positive, so urine protein is negative. If urine protein exceeds 150mg, urine protein positive results are presented. This situation distinguishes between physiological proteinuria and pathological proteinuria. Physiological proteinuria is mostly caused by cold, strenuous exercise, fever, cold, etc. After the influencing factors are removed, it can return to normal. Urine protein is generally presented (+).
