Biochemical liver abnormalities in LCMV-infected rhesus macaques. Markers of hepatocellular necrosis (AST, ALT), cholestatis (GGTP, bilirubin, alkaline phosphatase), and hepatic synthetic activity (albumin) were measured in plasma samples collected from WE- and ARM-infected monkeys. References ranges are 18–82, 22–87, 28–86 IU/L for AST, ALT, and GGTP, respectively; 0.1–<0.3 mg/dL, 30–120 IU/L, and 4.0–6.0 g/dL for bilirubin, alkaline phosphatase and albumin, respectively [12]
