Purpose: The aim of this study is to analyze the serum cystatin C (Cys C) and cystatin C/albumin (Alb) ratio in patients with cirrhosis and evaluate the role of serum Cys C in the evaluation of liver function. Methods: The liver function of patients was graded according to the Child-Pugh Score. According to the serum Cys C levels (determined with particle-enhanced immunonephelometric assay), the patients were divided into two groups: the high Cys C level group and normal Cys C level group. The correlation between the Child-Pugh grades/scores and the serum Cys C level, Cys C/Alb ratio were investigated. Results: The Cys C values were not correlated to Child-Pugh grades and scores. Besides, the Cys C/Alb ratio of both groups had a linear regressive relationship with the Child-Pugh scores. Ninety-seven percentage sensitivity and 100% specificity were achieved for the evaluation of liver function in cirrhosis patients with high serum Cys C level.
