title: The predictive value of microalbuminuria.
abstract: An elevated urinary albumin excretion (termed microalbuminuria) has been proposed as a predictor for later development of clinical diabetic nephropathy (hypertension, falling glomerular filtration rate [GFR], and urinary albumin excretion greater than 300 mg/24 h). However, review of the original reports on the predictability of microalbuminuria revealed a concomitant presence of elevated BP and a propensity to falling GFR. Thus, the predictability of microalbuminuria rests on the added evaluation of BP and GFR. Additional investigation is needed to address the possibility that microalbuminuria and either a rising BP or a falling GFR or both indicates established diabetic nephropathy rather than predicting its development.
