What is the purpose of this test?
The Protein Total Urine Test, Quantitative, 24-Hour measures the amount of protein in urine over a full day to assess kidney function and detect conditions that cause abnormal protein levels. The kidneys normally filter and retain proteins, but when they are damaged or not functioning properly, protein can leak into the urine. This test helps identify conditions like kidney disease, diabetes, high blood pressure, or other underlying disorders that may impact kidney health.
Monitoring protein levels in urine is crucial for diagnosing and managing kidney-related conditions. Elevated protein in urine, known as proteinuria, can signal early kidney damage, while low levels might suggest other metabolic or nutritional imbalances. By providing a comprehensive assessment over 24 hours, this test offers more accurate insights into kidney function compared to random urine samples.
Who should get this test?
- Individuals with known kidney disease or chronic kidney conditions.
- People with diabetes or high blood pressure, as these conditions can harm the kidneys.
- Those experiencing symptoms like swelling in the hands, feet, or face, or frothy urine.
- Individuals with a family history of kidney disease.
- People undergoing treatment for kidney disorders to monitor progress.
- Anyone with abnormal results on a routine urine dipstick test.
