[Disease biomarkers for CKD].

As novel urinary biomarkers for kidney injury, neutrophil gelatinase-associated lipocalin (Ngal), kidney injury molecule-1 (KIM-1), liver-type fatty acid binding protein(L-FABP) et al. have emerged. Recent studies elucidated their usefulness in chronic kidney disease and acute kidney injury. Meanwhile, the understanding of clinical significance of albuminuria, a classical biomarker, has changed as well. In this review, the progress and current status of urinary biomarker research in the field of chronic kidney disease will be described and future problems to be solved will be discussed.
