GPT and Hepatic fibrosis: Our results indicate (Table 2) that an HA level ≥ 34.2 ng/mL associated with ALT > 40 UI/L correctly identified HCV infection (sensitivity = 96% and specificity = 90%) and could potentially identify liver fibrosis with high certainty (AUROC = 0.88) in blood donors with asymptomatic HCV infection.
