This test is a highly sensitive, early-warning system for your kidney health. It is designed to detect very small amounts of protein (microprotein) in your urine, which are often the first sign of kidney damage, long before you would feel any symptoms. Healthy kidneys should keep protein in your blood, so any amount in the urine signals a need for investigation. This test requires you to collect all urine passed over a 24-hour period. Proactive health is in the details. This test provides the critical, early data you need to protect your kidneys for the long term.
