Logistic regression analysis revealed that liver enzymes (ALT, AST, ALP, γGT, albumin), blood cell count (globulin, platelets, MCHC RBC, WBC, monocytes% and lymphocytes%), lipid profile (HDL, LDL, VLDL, TC) were significant predictive factors in HCV infection. Similarly, ROC analysis suggested that ALT, AST, ALP, MCHC, TC, and VLDL variables have the potential to discriminate HCV infection from healthy individuals. Biochemical markers lik...
