The Urine Transferrin Test is very helpful in identifying any disturbances in kidney function early on. High levels of transferrin also indicate a higher inflammatory response in the body, which can be a result of an acute or chronic illness. People with uncontrolled diabetes, high blood pressure, and autoimmune disorders like lupus are at a higher risk of kidney disease and must speak to their doctor for routine health check-ups, including kidney function. This test can be taken by people of all age groups on doctor’s advice.
