Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like swelling in your legs, frequent urination, or unexplained weight changes. It’s also used during pregnancy to monitor kidney health or if you have a history of kidney disease, diabetes, or high blood pressure.

What to Expect During the Test

You’ll likely collect a midstream urine sample in a clean container. The test is quick and painless, and results are usually available within a few hours or the next day.

How the Results Are Interpreted

Results are qualitative (positive or negative) rather than a specific number. A positive result means protein is present in your urine, which may need further evaluation by your doctor.

Common Reasons for Positive Results

Positive protein in urine can occur due to kidney problems, infections, or conditions like diabetes. It may also be temporary, such as after exercise or fever.
