People with proteinuria have urine containing an abnormal amount of protein. The condition is often a sign of kidney disease. Healthy kidneys do not allow a significant amount of protein to pass through their filters. But filters damaged by kidney disease may let proteins such as albumin leak from the blood into the urine. Proteinuria can also be a result of overproduction of proteins by the body. Kidney disease often has no early symptoms. One of its first signs may be proteinuria that's discovered by a urine test done during a routine physical exam. Symptoms and signs of proteinuria in TCM include.
