Microalbumin/Creatinine Ratio Urine Test, Random

What are microalbumin and creatinine?

Albumin, also known as microalbumin, is the primary protein found in the blood. When healthy kidneys expel waste from the blood, tiny filters control large albumin molecules from escaping the body in urine. Usually, just a trace of albumin, or none, will get through the filters. However, if the kidneys are damaged, more significant amounts of albumin may pass into the urine.

Creatinine is a byproduct in urine from day-to-day wear and tear on the muscles. A microalbumin creatinine ratio test assists in comparing albumin levels to creatinine levels in the urine. This method is more precise in measuring the albumin levels in the urine.
