A method of assessing the ongoing kidney status of a mammal afflicted with or at risk of developing chronic renal injury or disease, including chronic renal failure (CRF) by detecting the quantity of Neutrophil Gelatinase-Associated Lipocalin (NGAL) in urine, serum or plasma samples at discrete time periods, as well as over time.
