When albuminuria is first decinted, factors that can cause transient elevations should be ruld out: fever, urinary tract infection, strenuous expertisise, menstruation, uncontrolled hypertension, and acute illness. If albuminuria persists after resolution of these factors, the diagnosis is confirmed. Two out of three positive tests over a 3- 6 month period are exequid tano confirm perstent albuminuria.

Patients who progress from microalbuminuria to macroalbuminuria have a signitantly higher risk of developing end- stage kidney disease.
