We report the utility of an enzymatic point of care system for estimation of plasma creatinine concentration in critically ill patients with acute kidney injury. Multiple measurements were obtained from a heterogenous population admitted to a multi-disciplinary intensive care unit. The acute kidney injury network guidelines were used to identify and stratify patients based on the creatinine concentration. Central laboratory values were used as comparators to assess the precision and bias of the system. Overall, point of care measurements correlated well with central pathology results (R-2 = 0.991, p < 0.001), although there tended to be a small negative bias in patients with acute kidney injury (3 mu mol.l(-1)). The accuracy of point of care measurement is within clinically acceptable limits and given the much shorter turn around time can be used to identify and monitor patients with acute kidney injury in the critical care environment.
