![]() Since then, it has evolved to exclude causes of disease and takes into account the serum sodium level and whether the patient is on dialysis. The original MELD score calculation used the patient's bilirubin level, creatinine level, INR, and cause of liver disease. The MELD score, which has a broader range of more continuous variable values, was created to account for these differences. Practically speaking, a patient with an INR of 6 and bilirubin of 14 could potentially have the same Child-Pugh score as a patient with an INR of 2.3 and bilirubin of 4.0. This last limitation was significant because patients were not able to be adequately differentiated based on the severity of the disease, and therefore wait time had a considerable impact on prioritization. Laboratory values less than 1.0 are set to 1.0 for the purposes of the MELD score calculation. Multiply the score by 10 and round to the nearest whole number. 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. The original MELD score is calculated using the following formula: MELD Score 0.957 x Log (creatinine mg/dL) + 0.378 x Log (bilirubin mg/dL) + 1.120 x Log (INR) + 0.6431. However, there were three primary limitations to its use: 1) grading ascites and encephalopathy require a subjective assessment, 2) the classification system does not account for renal function, and 3) there are only ten different scores (based on points) available. The SAFE (Steatosis-associated Fibrosis Estimator) score is a scoring system to categorize NAFLD patients by their risk of having significant liver fibrosis (stage 2 or higher) and long-term outcome. doi:10.1038/s4139-9.Historically the Child-Pugh classification was used for liver transplant allocations.

Liver function tests in identifying patients with liver disease. Correction factor to improve agreement between point-of-care and laboratory International Normalized Ratio values. The mean MELD score (14.1) and MELD-Na score (17.1) were relatively well-preserved, limiting conclusions for patients with very elevated MELD or MELD-Na scores.

Determinationedit MELD uses the patients values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival.
