Range of microalbuminuria is?

Systemic hypeension causes major effects in three main organs--hea and its blood vessels, nervous system, and kidneys. An impoant and early clinical marker for renal injury from hypeension and risk factor for cardiovascular disease is macroalbuminuria (i.e. albuminuria > 150 mg/day or random urine albumin/creatinine ratio of >300 mg/gm creatinine), or microalbuminuria estimated by radioimmunoassay (i.e. microalbumin 30-300 mg/day or random urine microalbumin/creatinine ratio of 30-300 mg/gm creatinine).
