Because of the risk of nephropathy, monitoring renal function is critical in diabetes management. Renal failure occurs more often in type 1 diabetes but because of the greater incidence of type 2 diabetics, a larger number of type 2 individuals are among those with diabetic nephropathy. Diabetic urinary albumin levels are monitored with urinary albumin excretion (UAE); these assays are referred to as microalbuminuria testing.
