  • FIB-4 Index

    A score worked out from your age, AST, ALT and platelet count. It helps estimate the chance of advanced scarring (fibrosis) in the liver.

    18–64
    up to 1.3 index
    65+
    up to 2 index

    8–48 U/L
    Women, 14+
    8–43 U/L

  • Alanine Aminotransferase (ALT)

    An enzyme made mostly in liver cells. It leaks into the blood when liver cells are irritated or damaged.

    Men, 18+
    0–44 U/L
    Women, 18+
    0–32 U/L

  • Platelet Count

    The number of platelets, the small blood cells that help your blood clot, in a sample of your blood.

    Adults
    150–450 ×10³/µL

  • Enhanced Liver Fibrosis (ELF) Score

    A blood score made from three proteins linked to liver scarring. It helps estimate the risk of advanced scarring and of liver problems getting worse.

    Men
    7–9.9 score
    Women
    6.6–9.3 score
