Serum cystatin C is an early biomarker for assessment of renal function in burn patients.

Background: Early detection of renal dysfunction is important in burn patients. This study evaluated whether serum cystatin C (CysC) is a potentially accurate and sensitive marker for identification of reduced glomerular filtration rate (GFR) and the risk factors of impaired renal function in major burn patients.

Methods: A total of 48 adult patients with major burn injury were enrolled.
