Additional Information

Measures small amounts of albumin that may be present in the urine.  Used for early detection and monitoring of Diabetic Nephropathy.  Diabetes is now the most common cause of end stage renal disease (ESRD).  About 20%-30% of patients with Type I and Type II diabetes develop evidence of nephropathy.  If left untreated, a significant number of these patients will progress to ESRD. Early intervention has the greatest impact on improving the course of diabetic nephropathy.  Type II diabetics should be screened for microalbuminuria at the time of diagnosis and annually thereafter.  Microalbuminuria rarely occurs with Type I diabetics of short duration.  Microalbumin screening with Type I diabetics should be performed annually beginning after 5 years of disease onset.
