Reference Notes and Guidelines

1. This test is used to aid the diagnosis and to monitor chronic kidney disease. Change in albumin levels may reflect response to therapy and risk for progression of disease.

2. Microalbumin is a term used to describe urine albumin levels not detected by a dipstick test. Macroalbuminuria is used to describe albumin levels that can be detected by dipstick (see table above for approximate levels).

3. A decrease in urine albumin may be associated with improved renal and cardiovascular outcomes.
