<prompt> Range of microalbuminuria is?10-99 mgday20-199 mgday30-299 mgday40-399 mgday  <response>: 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 mgday or random urine albumincreatinine ratio of 300 mggm creatinine, or microalbuminuria estimated by radioimmunoassay i.e. microalbumin 30-300 mgday or random urine microalbumincreatinine ratio of 30-300 mggm creatinine.
