Why This Test Is Done
Your healthcare provider may order this test to check for signs of kidney disease, such as proteinuria (excess protein in urine). It can also help monitor conditions like diabetes, high blood pressure, or kidney damage from other illnesses. Sometimes, it’s used to screen for conditions that affect how your body filters waste from blood.
What to Expect Before the Test
No special preparation is usually needed. You may be asked to collect a urine sample in the morning or at a specific time. Avoid strenuous exercise or certain foods (like large amounts of salt or protein-rich foods) for 24 hours before testing if instructed by your provider.
What Happens During the Test
You’ll provide a small sample of urine, which is then tested in a lab to measure protein levels. The test can be done quickly, often as part of a routine urine dipstick or a more detailed lab analysis.
What the Results Mean
Higher-than-normal protein levels in urine may indicate kidney problems, inflammation, or other health issues. Your provider will interpret the results in the context of your medical history and other tests. Normal results suggest no significant protein loss in urine.
