MELD Score Calculator (MELD, MELD-Na, MELD 3.0)

Your details

MELD 3.0 is the current OPTN/UNOS standard. MELD-Na was used from January 2016 to 2022. The original MELD is retained for historical and international use.
MELD 3.0 adds 1.33 points for female sex to correct for historical transplant access disparity.
If the patient received dialysis at least twice in the past 7 days, check the dialysis box; creatinine will be set to 4.0 mg/dL per OPTN rules.
mg/dL
When checked, creatinine is set to 4.0 mg/dL regardless of the lab value, per OPTN/UNOS allocation policy.
Total serum bilirubin. Values below 1.0 mg/dL are set to 1.0 in the OPTN formula.
mg/dL
International Normalized Ratio for prothrombin time. Values below 1.0 are set to 1.0.
For MELD 3.0, sodium is clamped to 125-137 mEq/L.
mEq/L
MELD 3.0 only. Clamped to 1.5-3.5 g/dL. Values above 3.5 are set to 3.5 (no protective effect beyond normal).

MELD 3.0 score: 15 (~6.0% 90-day waitlist mortality)

  • A score of 15 corresponds to an estimated 90-day waitlist mortality of ~6.0% without transplant.
  • Research shows the survival benefit of liver transplantation begins to exceed its surgical mortality risk at a score of 15 or higher. Patients at this threshold or above are generally considered strong candidates for active transplant listing.
  • MELD 3.0 adds serum albumin and a sex-based adjustment to correct for the historical underrepresentation of female patients in transplant allocation. It is the current OPTN/UNOS standard as of July 2022.

Next stepDiscuss these results with a hepatologist or transplant center. The MELD score is one input among many; exception points, clinical status, and center-specific thresholds all affect actual listing decisions.
