Proteins in Urine

The proteins in urine test is used to detect and measure proteins, including albumin, in the urine. This test is crucial for diagnosing and monitoring various conditions, particularly those affecting the kidneys. It is available at IntroLab, a private laboratory in Belgrade.

What are proteins?

Proteins are essential components of all living organisms and play a crucial role in most biological processes. However, the presence of proteins in urine (proteinuria) can indicate certain health issues, particularly kidney diseases.

Types of proteinuria

There are three main types of proteinuria: transient, orthostatic, and persistent.

• Transient Proteinuria is the most common type and usually resolves without treatment. It can occur due to factors such as high fever, intense physical activity, or urinary infections.
• Orthostatic Proteinuria occurs only when a person is standing or sitting and disappears when lying down. It affects 2-5% of adults but is rare in individuals over 30 years old. The cause of orthostatic proteinuria is unknown. It is not harmful, does not require treatment, and typically resolves with age. Diagnosis involves collecting urine separately during the day (standing/sitting) and night (after sleeping).
• Persistent proteinuria occurs in patients with kidney or other conditions, such as diabetes, hypertension, or bone marrow disorders like multiple myeloma.

How is the test performed?

The test involves providing a urine sample. A laboratory technician uses a test strip with a sensitive area that changes color when proteins are present. The color change on the strip indicates the level of proteins in your urine.

Preparing for the test

Before the test, inform your doctor about all medications you are taking, as some can affect the results. Several factors can influence the outcome of the urine protein test, including dehydration, use of contrast agents for radiological exams, physical activity and urinary tract infections.

Interpretation of results

Normal protein levels in urine vary, but for a random urine sample, they typically range from 0 to 14 mg/dL. Higher than normal protein levels in your urine can indicate conditions such as kidney disease, heart failure, pregnancy complications, and urinary infections.

Risks associated with the proteins in urine test

The proteins in urine test is safe and risk-free. It involves normal urination, so there is no discomfort involved.
