ALB and diabetic kidney disease: Traditionally, DKD was defined as a sequential evolution of stages where the onset would be characterized by glomerular hyperfiltration and renal hypertrophy, followed by a progressive increase in urinary albumin excretion (UAE) between 30 mg/day and 300 mg/day (formerly known as microalbuminuria) and subsequently by UAE greater than 300 mg/day or macroalbuminuria.
