Instead to the SI units version of this calculator. You are using SI units (Système international d'unités) please refer The Organ Procurement & Transplantation Network (OPTN) provides a MELD calculator and a PELD calculator for people to calculate. MELD 3.0 Calculator mg/dL mEq/L mg/dL g/dL Scores Original MELD 0 MELD Na (UNOS version) 0 MELD 3.0 0 Introduction: The Model for End-Stage Liver Disease (MELD) is a prognostic score to measure the severity of liver failure and thus to estimate short term survival in patients with chronic liver disease. Scoring system used to rank prioritize candidates for liver transplantation, including MELD-Na used in the OPTN match system.

To calculate an approximate lung Composite Allocation Score (CAS) range, enter data for each variable. Calculate by QxMD provides free decision support tools and medical calculators for web, iOS and Android. It uses the same formula that is used for the lung allocation policy that took effect March 9, 2023. Therefore, the new formula where original MELD score is MELD(i) is: MELD Score (2016) MELD(i) + 1.32 x (137-Na) 0.

* This calculator uses conventional units (also known as US unitsĪnd gravimetric units) as the default for inputs. This is a sample calculator to show how the lung Composite Allocation Score (lung CAS) is established. In January 2016, OPTN changed Policy 9.1 in regard to the calculation of the MELD score to include serum sodium.

Please refer to appropriate UpToDate topic reviews for further information.

INR: international normalized ratio Serum Na: serum sodium concentration CVVHD: continuous venovenous hemodialysis.

Additional information about the MELD scores is at the UNOS website.

When used for liver transplantation listing, UNOS/Organ Procurement and Transplantation Network (OPTN) sets the upper limit for the MELD score at 40. Read more about MELD and use the online MELD calculator on the Organ Procurement and Transplantation Network (OPTN) website.

About MELD and PELD The MELD and PELD calculators are used for liver allocation in the OPTN match system.

For patients with hepatocellular carcinoma, the MELD score is increased according to an algorithm established by the United Network for Organ Sharing (UNOS). MELD calculator To determine your MELD score, please complete the form below.

If a patient has had 2 or more hemodialysis treatments or ≥24 hours of CVVHD in the week prior to the time of the scoring, Creatinine will be set to 4 mg/dL, which is the maximum creatinine level allowed in the model.

The default setting for the choice "Hemodialysis twice or ≥24 hours of CVVHD in the past week" is "No.".

Hyponatremia contributes to the MELDNa score only when the initial MELD score is greater than 11.The MELDNa score system adds a Serum Na parameter, so the added risk of significant hyponatremia may be taken into account.The model for end-stage liver disease ( MELD) score is used to estimate relative disease severity and likely survival of adult patients awaiting liver transplantation.
