What is Protein in Urine?

Protein in urine, also known as proteinuria, is an excess of protein found in a urine sample that signifies an underlying medical disorder. Urine tests can not only detect protein in urine, but can also measure the exact amount present. An abnormal amount of protein in the urine may signal a kidney or heart disorder.


No preparation is necessary before a urine protein test.


A urine protein test is a simple test. A healthcare professional will collect a urine sample from the patient. The urine sample is then sent to a laboratory where it is tested for the presence of proteins. The results of the test will indicate whether there is an abnormal amount of protein in the urine.


There are two types of urine protein tests: qualitative and quantitative. A qualitative test will tell you whether protein is present in the urine, while a quantitative test can measure the exact amount of proteins present.


A urine protein test is typically a safe test. There is minimal risk associated with the test, which involves collecting a urine sample from the patient.

Why it's done

A urine protein test is done to detect an underlying medical disorder. Proteinuria can be an indication of kidney or heart problems.

When to consider it

A urine protein test may be considered when a patient has symptoms of kidney or heart disorders, such as high blood pressure, shortness of breath, or swelling in the extremities.
