Common questions
What does MELD-Na Score Calculator do?
Prognosis and liver-transplant prioritisation.
How is the result calculated?
MELD = 3.78·ln(bilirubin) + 11.2·ln(INR) + 9.57·ln(creatinine) + 6.43; labs floored at 1.0, creatinine capped at 4.0 (or with dialysis). MELD-Na adds a sodium term when MELD > 11.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
