In the Framingham Heart Study, it was shown that healthy individuals (defined as non-hypertensive, non-diabetic, and without prevalent CVD) with elevated microalbumin levels had approximately 3x greater risk for developing cardiovascular disease. These levels were gender-specific and noted to be ≥3.9 mg/g cr for men and ≥7.5 mg/g cr for women (1).  A persistent  microalbumin of >30 mg/g cr indicates a loss in kidney function and is used in the diagnosis of chronic kidney disease (2). (References: 1-Arnlov et al. Circulation 2005; 112:969-975. 2-Fox et al. Nephrology 2013; 1:21.)

Clinical Significance: The urinary microalbumin/creatinine may be performed on individuals with type 1 or type 2 diabetes, hypertension, a family history of chronic kidney disease, those at intermediate (10-20%) risk for cardiovascular disease or those with known vascular disease.
