microalbumin urine range
Reference Range. Microalbuminuria is defined as excretion of 30â300 mg of albumin per 24 hours (or 20â200 mcg/min or 30â300 mcg/mg creatinine) on 2 of 3 urine collections. The detection of low levels of albumin excretion (microalbuminuria) has been linked to the identification of incipient diabetic kidney disease.
