Serum cystatin C for prediction of dialysis requirement or death in acute kidney injury: a comparative study.
Serum cystatin C has emerged as a new and potentially more reliable marker of kidney function. However, its utility and performance in patients with acute kidney injury (AKI), particularly for the prediction of dialysis requirement, is not well known. ⋯ In patients with AKI, serum cystatin C level performs similarly to serum creatinine level, serum urea nitrogen level, and urine output for predicting dialysis requirement or in-hospital death. Larger studies are needed to confirm these findings.
