  • Urine Microalbumin
  • Albumin-to-Creatinine Ratio (ACR)
  • M/C Ratio

Albumin is a protein normally found in blood but not in urine. An early indication of kidney disease is the presence of small (micro) amounts of albumin in the urine. When MA is detected in the urine of people with diabetes mellitus (DM), the amount measured is related to the length of time you have had the disease and how well you have been able to control your blood sugar (glucose) levels over time. High urine levels of MA can be an indication of a high risk for the development of complications of DM (diabetic neuropathy, sever kidney failure, cardiovascular disease, and retinopathy) years before physical symptoms are seen. MA in the urine is also an indication of kidney failure that is not caused by DM. For people without DM, the presence of MA in their urine is an indication of an increased risk for the development of complications of hypertension and CVD (cardiovascular disease), and levels can actually be used to determine life expectancy.
