How much protein in your urine is normal?

Healthcare professionals usually use the urine albumin-to-creatinine ratio (uACR) test to get an accurate count of proteins in urine.

Albumin is the most abundant protein circulating in your blood plasma. Doctors often use the terms “proteinuria” and “albuminuria” interchangeably. Higher levels of albumin in your urine are usually a sign that your kidneys aren’t working properly.

According to the National Kidney Foundation, a reading of 30 milligrams of protein per gram of creatinine (mg/g) or less in your urine is normal and not usually a cause for concern.

If a healthcare professional finds higher amounts of protein in multiple urine tests over time, or the protein levels in your urine are increasing, they may want to perform additional testing or check your urine more frequently.

Increased levels over more than 3 months can indicate chronic kidney disease (CKD).

Other tests

Doctors sometimes use other tests to determine protein levels.

The urine protein-to-creatine ratio (uPCR) test measures all protein in your urine, not just albumin. Doctors use the uPCR in testing children or people with certain forms of kidney disease. Doctors interpret results as follows:

uPCR resultWhat it meansless than 150 mg/gnormal or mildly increased protein levels150 to 500 mg/gmoderately increased protein levelsmore than 500 mg/gseverely increased protein levels

The 24-hour urine protein test measures the protein in your total urine output over a 24-hour period. While the uACR and uPCR measure a single sample, this test measures a collection (often one large jug) of all the urine you produce over 24 hours.

If your total protein levels are higher than 150 mg over 24 hours, doctors consider this proteinuria and may request further testing.
