The 24-hour urine creatinine test measures the amount of creatinine excreted in urine over a full day. Creatinine is a waste product formed by muscle metabolism and is filtered by the kidneys. This test helps evaluate kidney function and detect possible kidney diseases or disorders affecting filtration.
This test is commonly recommended for individuals experiencing symptoms like swelling (edema), fatigue, frequent urination, or high blood pressure, which may indicate kidney dysfunction. It is also used to assess the effectiveness of treatment in people with chronic kidney disease (CKD) or other renal conditions.
The test requires collecting urine over 24 hours in a specialized container. Patients must follow instructions carefully to ensure accurate results. Proper storage of the sample during the collection period is essential. Unlike blood creatinine tests, the 24-hour urine test provides a more precise measure of how well the kidneys are clearing waste from the body.
This test is suitable for all age groups, particularly those at risk of kidney disease, such as individuals with diabetes, hypertension, or a family history of kidney disorders. Since kidney function is crucial for overall health, consulting a doctor for result interpretation and further medical advice is necessary. Treatment options may include dietary changes, medications, or lifestyle modifications based on the findings.
