    Advice

    Patients should be evaluated for transplant if no reversible causes of cirrhosis can be identified.

    Formula

    MELD-Na = MELD Score - Na - 0.025*MELD*(140-Na) + 140

    Facts & Figures

    • Sodium is limited in a range of 125-140, and if outside of these bounds, is set to the nearest limit.
    • The MELD-Na has been found to have a better fit for mortality prediction compared to the MELD score alone.
