If a test is done and urine protein is found to be weakly positive, it suggests that there is a small amount of protein in the urine. The normal amount of protein in urine is less than 150mg in 24 hours, which is a normal physiological manifestation when you have a weak positive urine protein test, which can be seen during strenuous exercise, nervousness, cold and flu. However, if it is accompanied by other uncomfortable symptoms or bad test results, it may be caused by some diseases, such as glomerular and tubular lesions, which can also cause weak positive urine protein, this situation needs to go to the nephrology department for further clarification and targeted treatment.
