Microalbuminuria is defined as excretion of 30–300 mg of albumin per 24 hours (or 20–200 mcg/min or 30–300 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.
Albumin is a protein which is present in the blood. The kidneys act as a filter for waste products in the blood. Protein is not allowed to spill over into the urine unless the filter system is ‘leaky’. Microalbuminuria refers to the appearance of small but abnormal amounts of albumin in the urine. Patient information: See related handout on diabetic nephropathy, written by the author of this article. Diabetic nephropathy, or diabetic kidney disease, affects 20 to 30 percent of patients with diabetes. It is a common cause of kidney failure. As with most complications of diabetes, there is no definitive “cure” for diabetic nephropathy. However, a recent study 4 followed nearly 400 patients with type 1 diabetes and micro-albuminuria for six years, and more than one half of the patients in the study experienced regression of microalbuminuria. Reference Range. Microalbuminuria is defined as excretion of 30–300 mg of albumin per 24 hours (or 20–200 mcg/min or 30–300 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. Background. Microalbuminuria is defined as excretion of 30–300 mg of albumin per 24 hours (or 20–200 mcg/min or 30–300 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. Diabetic nephropathy presents in its earliest stage with low levels of albumin (microalbuminuria) in the urine. The most practical method of screening for microalbuminuria is to assess the albumin-to-creatinine ratio with a spot urine test. Results of two of three tests for microalbuminuria should be more than 30 mg per day or 20 mcg per minute in a three-to six-month period to diagnose a patient with diabetic nephropathy. As with most complications of diabetes, there is no definitive “cure” for diabetic nephropathy. However, a recent study 4 followed nearly 400 patients with type 1 diabetes and micro-albuminuria for six years, and more than one half of the patients in the study experienced regression of microalbuminuria. A American Diabetes Association answered. Microalbuminuria is the presence of small amounts of albumin, a protein, in the urine. Microalbuminuria is an early sign of kidney damage, or nephropathy, a common and serious complication of diabetes.  Microalbuminuria is likely to be found in one-third or more of diabetic patients. Microalbuminuria is a risk factor for cardiovascular and renal disease. Antiangiotensin therapy and blood pressure control can reduce urine albumin levels and give renal protection. Patients with diabetes are at risk of microalbuminuria if they have any of the following factors: · the urine albumin excretion is in the upper range of normal (20–30 mg/d); · the systolic blood pressure is greater than 130 mm Hg; Microalbuminuria is a term to describe a moderate increase in the level of urine albumin. It occurs when the kidney leaks small amounts of albumin into the urine, in other words, when there is an abnormally high permeability for albumin in the glomerulus of the kidney. The term 'microalbuminuria' is now discouraged by KDIGO (Kidney Disease Improving Global Outcomes) and has been replaced by 'moderately increased albuminuria'. microalbuminuria. Nephrology The excretion of 30-300 mg albumin/day; ↑ albumin excretion predicts hemodynamic and morphologic changes of diabetic nephropathy; when ↑, is an early indicator of renal failure the risk of microalbuminuria in DM ↑ when Hb A1 Diabetic nephropathy.  Microalbuminuria: 1. Generally, a subtle increase in the urinary excretion of the protein albumin that cannot be detected by a conventional assay. In diabetes, microalbuminuria is an early sign of diabetic kidney disease. 2. Specifically, the excretion of greater than 30 mg and less than 300 mg a day of albumin in the urine. The normal urinary albumin is less than 30 mg per 24 hours and 300 mg or more of urinary albumin per day is considered gross albuminuria
