What does urine routine protein-0 mean?

In urine routine examination, protein test results are usually expressed in numbers. In the results, if the protein value is 0, it means that protein is not detected in urine.

Under normal circumstances, there is only a trace of protein in urine of healthy people. If the results of multiple urine tests show protein is 0, it is usually considered normal and there is no abnormal protein excretion. It implies that the filtration function of the kidney is normal and there is no obvious protein leakage. The presence of protein in urine may be caused by strenuous exercise, stress, nephritis, kidney tumor and other factors.

If the specific cause needs to be clarified, it needs to be further judged by B ultrasound, CT examination, tissue biopsy, etc.
