To put it in simple, kidneys are organs which play the function of secreting, adjusting and filtration. If you have protein or blood in urine, it means that now the function of filtration has been damaged.
Proteinuria includes physiological proteinuria and pathological proteinuria. Physiological proteinuria refers to proteinuria in urine due to some transient factors; it can disappear when one changes position. Functional proteinuria occurs after one has strenuous exercise, fever, or a cold. When his or her temperature goes down to normal level, proteinuria will disappear. Pathological proteinuria refers to proteinuria when kidney disease or kidney damage involved in systemic disease.
