ALB and urinary tract infection: The term microalbuminuria is defined by a urinary albumin excretion (UAE) rate higher than normal but lower than 200 μg/min, the lowest detection limit of proteinuria as measured by standard laboratory methods[1, 2] in the absence of urinary tract infection and acute illness including myocardial infarction.[3] Albumin excretion in healthy individuals ranges from 1.5–20 μg/ min.[4] The presence of microalbuminuria precedes the development of overt diabetic nephropathy by 10–14 years.
