Answer

Perform microscopic urinalysis to help rule out a potentially nephritic picture, which may lead to a workup to rule out other primary glomerulopathies, especially in the setting of rapidly deteriorating renal function (eg, rapidly progressive glomerulonephritis). In general, onset of overt proteinuria with less than 5 years of the onset of diabetes, an active urine sediment with dysmorphic red cells and casts, or an abrupt decline in kidney function suggests a nondiabetic etiology of the kidney disease.
