This test provides a comprehensive and highly accurate assessment of your kidney health. It precisely measures the amount of protein being lost through your kidneys over a 24-hour period, using the creatinine level to ensure the most accurate result. This is a crucial test for detecting and monitoring kidney damage (nephropathy), often caused by diabetes or high blood pressure. The test requires you to collect all urine passed over a 24-hour period in a special container we provide. This method provides a complete picture that a single spot test cannot. This is a definitive, gold-standard test for managing and protecting your kidney function.
