The authors found that uCysC measured at ICU admission was indepen-dently associated with sepsis (OR 3.43), AKI (OR 1.49), and mortality (OR 1.6) and that uCysC concen tra tions were significantly higher in the presence of sepsis or AKI. uCysC was predictive of sepsis with an optimal cut-point of 0.24 mg/L. In the sepsis group, however, diagnostic
performance of uCysC for AKI was not significant but was predictive of AKI within 48 hours.
