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 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.
