In this study, it was found that there was significant difference in median fibronectin, pseudochoinesterase, prothrombin and equation levels with the degree of fibrosis, P<0.05. Also, when ROC, curve was poltted; it was found that the equation significantly was discriminate between fibrosis and cirrhosis at cut off value of 243.28{AUC= 0.802, SENSIVITY WAS 100% AND SPECIFICITY WAS 60%}. In our study, there was significant positive correlation between fibronectin and other parameters (pseudocholinestrase, prothrombin activity, ALP and albumin) (p < 0.05 each). Also, there was significant negative correlation between the equation and the degree of fibrosis; r= -0.642, p<0.
