Microalbumin Test

The presence of low levels of albumin (microalbumin) in the urine is an important finding in an individual with either type 1 or type 2 diabetes. The development of clinical nephropathy leads to reduced glomerular filtration and eventually may lead to renal failure. For this reason, early detection of microalbumin is important in order to avert renal complications in a diabetic patient.

The presence of microalbuminuria has also been associated with an increased risk for cardiovascular disease.

Reagent strips that are used for routine urinalysis cannot detect low levels of albumin excretion (1 to 2 mg/dL). Special reagent strips that are sensitive for these low levels of albumin are useful for periodic monitoring of patients with diabetes, hypertension, or peripheral vascular disease.
