What is the prognosis of proteinuria?

Proteinuria refers to the excretion of more than the normal amount of protein, usually albumin, by the kidneys. Most often this is first detected when a person submits a urine sample for analysis. A little extra protein in the urine may be present without any current or future kidney problem. Repeat urine testing should first be done to confirm the proteinuria. If confirmed, a blood test to measure kidney function should be the next step.
