The document summarizes evidence on the relationship between glycated hemoglobin (HbA1c) levels and microalbuminuria in monitoring diabetes. It finds: 1) HbA1c is strongly associated with increased risk of retinopathy and nephropathy. Risk rises with higher HbA1c levels. 2) Microalbuminuria is associated with increased risk of declining renal function and cardiovascular disease outcomes like death. However, studies have not systematically assessed the exact risk relationship or determined optimal definitions of microalbuminuria. 3) The report systematically reviews literature on glycemic control and microalbuminuria testing to evaluate their ability to predict diabetes complications and inform clinical guidelines.
