Comparison of urinary neutrophil glucosaminidase-associated lipocalin, cystatin C, and α1-microglobulin for early detection of acute renal injury after cardiac surgery

Abstract

An increase in urinary NGAL is an early sign of acute kidney injury after cardiac surgery. After multiplication by the serum/urine creatinine ratio, urinary α1MG is also suitable for detection of acute kidney injury at an early stage.
