What Is a Healthy Range of Protein in Urine?
The normal range for protein in urine is 20 milligrams per deciliter for a random urine sample, according to MedlinePlus. A doctor may order a 24-hour urine collection. With this test, normal ranges are less than 80 milligrams per 24 hours.
While small amounts of protein are normal in the urine, they are below the limits of the normal random urine test. Doctors order testing for protein in the urine as screening tests or because they suspect kidney damage, according to MedlinePlus. High levels of protein in the urine often indicate one of several conditions, including heart failure, kidney disease, dehydration or urinary infections. In pregnant women, high protein levels could indicate problems caused by the pregnancy, including seizures.
