NGAL (neutrophil gelatinase-associated lipocalin, lipocalin-2, siderocalin) is a small protein expressed in neutrophils and certain epithelia, including the renal tubules. Renal expression of NGAL is dramatically increased in kidney injury from a variety of causes, and NGAL is released into both urine and plasma.
