It combines four routine laboratory values \u2014 bilirubin, INR, creatinine and sodium \u2014 into a single number from 1 to 40. A higher score means more severe liver disease and a higher risk of dying within three months, which translates into higher priority on the transplant waiting list.<\/p>\n<p>The original MELD score used only bilirubin, INR and creatinine. However, low serum sodium (hyponatremia) was found to be an independent predictor of mortality in patients with cirrhosis and portal hypertension, so the sodium adjustment was added in 2016. Two patients with identical bilirubin, INR and creatinine values can have very different MELD-Na scores if their sodium levels differ: a sodium of 125 mEq\/L can raise the score by roughly 6\u201310 points depending on the underlying MELD, while a sodium of 137 or above adds nothing.<\/p>\n<p>The score is interpreted in broad bands. Below 15, liver function is relatively preserved and most centers do not list a patient for transplant, because the surgical risk would exceed the risk of the disease itself. Scores of 15\u201324 indicate moderate severity and usually trigger transplant evaluation. Scores of 25\u201334 indicate advanced disease with substantial short-term risk, and a score of 35 or above signals very advanced disease requiring urgent specialist care and high transplant priority.<\/p>\n<p>Because MELD-Na relies on objective lab values, it reduces subjectivity in organ allocation. It is also useful in clinical discussions as a common language for disease severity \u2014 but it is a statistical estimate for populations, not a prediction for any individual patient.<\/p>\n<h2>Assumptions, Limitations and Practical Tips<\/h2>\n<ul>\n<li><strong>Caps and floors matter.<\/strong> The calculator applies the official OPTN rules: bilirubin, INR and creatinine are floored at 1.0 (so values below 1.0 are treated as 1.0), creatinine is capped at 4.0 mg\/dL, and sodium is clamped to 125\u2013137 mEq\/L. Entering a sodium of 120 or 145 produces the same result as 125 or 137, respectively.<\/li>\n<li><strong>Dialysis status changes the result significantly.<\/strong> If the patient received dialysis at least twice in the week before the lab draw, creatinine is set to 4.0 mg\/dL regardless of the measured value. Always check this box when it applies.<\/li>\n<li><strong>Mortality figures are historical estimates.<\/strong> The percentages shown (about 1.9% for scores \u22649, 6.0% for 10\u201319, 19.6% for 20\u201329, 52.6% for 30\u201339 and 71.3% for 40) come from the original MELD validation cohorts. Modern treatment has improved survival in many bands.<\/li>\n<li><strong>The score does not capture everything.<\/strong> MELD-Na does not account for complications such as hepatic encephalopathy, variceal bleeding, hepatorenal syndrome in progress, or liver cancer (which is handled by a separate exception process). Patients with complicated disease may be sicker than their score suggests.<\/li>\n<li><strong>Use recent labs.<\/strong> Values from a single stable blood draw give the most meaningful result. If sodium or creatinine is changing rapidly, the score can shift noticeably from one week to the next.<\/li>\n<li><strong>This tool is not a diagnosis.<\/strong> A MELD-Na score is one input among many; discuss your results with a hepatologist or transplant center.
