Systemic and Urinary Neutrophil Gelatinase-Associated Lipocalins Are Poor Predictors of Acute Kidney Injury in Unselected Critically Ill Patients

Figure 1

Neutrophil gelatinase-associated lipocalin (NGAL) in serum and urine per RIFLE severity. On nonacute kidney injury (AKI) days NGAL in serum and urine was lower (𝑃<0.05) compared with days fulfilling the RIFLE_RISK, RIFLE_INJURY, and RIFLE_FAILURE criteria. Non-AKI patients, 𝑁=57; AKI patients 𝑁=31.
