What is a microalbumin creatinine ratio?
Microalbumin is a small amount of a protein called albumin. It is normally found in the blood.  Creatinine is a normal waste product found in urine. A microalbumin creatinine ratio compares the amount of albumin to the amount of creatinine in your urine.
If there is any albumin in your urine, the amount can vary greatly throughout the day. But creatinine is released as a steady rate.  Because of this, your health care provider can more accurately measure the amount of albumin by comparing it to the amount of creatinine in your urine. If albumin is found in your urine, it may mean you have a problem with your kidneys.
Other names: albumin-creatinine ratio; urine albumin; microalbumin, urine; ACR; UACR
