MICROALBUMIN/ CREATININE RATIO TEST

Microalbumin creatinine ratio urine test is a way of checking for very small amounts of a protein called albumin in a sample of your urine (pee). Small amounts of albumin in urine, sometimes called microalbumin, may be one of the first signs of kidney disease. If you find kidney disease early, you can get treatment before it gets worse. Albumin is the main protein found in the blood. When healthy kidneys clean waste from your blood, tiny filters prevent large albumin molecules from leaving your body in urine. Normally, just a trace of albumin, or none at all, will get through the filters. But if your kidneys are damaged, larger amounts of albumin may pass into your urine. Creatinine is a normal waste product in urine that comes from daily wear and tear on your muscles. A microalbumin creatinine ratio test compares the amount of albumin to the amount of creatinine in your urine. This is a more accurate way to measure the amount of albumin in your urine.
