Urine Microalbumin/Creatinine Ratio (ACR)
The Urine Microalbumin/Creatinine Ratio (ACR) test detects the presence of tiny particles of protein in the urine, and is useful for identifying early signs of kidney damage, especially in persons with underlying disease like hypertension, diabetes or congenital kidney disease.
An elevated ACR level should be followed up with a doctor.
