Are serum and urine neutrophil gelatinase-associated lipocalin predictive of renal graft function in short term?

NGAL is a member of the lipocalin protein family that has diverse function but similar structure. The functions of NGAL are not clear, but it appears to be expressed in stress conditions and in tissues undergoing involution. Varied studies have shown increased levels of plasma or urinary NGAL in diverse renal damages.
