Clinical Significance

Microalbuminuria is the term given to the condition of increased excretion of albumin in urine. High urinary microalbumin is an early marker for renal disease. Measurement of microalbumin levels in urine are used to predict the development of diabetic nephropathy, as this protein tends to appear ahead of other serum proteins in urine during the course of renal glomerular damage. Measurement of microalbumin is therefore considered a standard for the detection of diabetic complications.
