Creatinine level, which is related to how well your kidneys are working.Your MELD score is based on results from several lab tests, including your: Your MELD score is one of several things that tells your place on the list. If your doctor says you need a liver transplant, you’ll be added to a waiting list managed by a national organization called the United Network for Organ Sharing. Reasons why you might need a liver transplant include having conditions that cause liver failure, such as: The higher the number, the more urgent your case is. It ranks your degree of sickness, which shows how much you need a liver transplant. MELD stands for 'model for end-stage liver disease.' Doctors use a similar system, called PELD (pediatric end-stage liver disease), for children younger than 12.Ī MELD score is a number that ranges from 6 to 40, based on lab tests.

If you’re an adult with liver disease that may call for a transplant, your MELD score helps to tell how quickly you might need it.

The 3 month mortality prediction as per the MELD definition in regard to waiting list mortality is listed below: The commonly met score range is usually between 6 and 40 but extremes can become apparent. The MELD models are basically a severity index by the United Network for Organ Sharing (UNOS) that allows a prioritization of organ transplant by showing the mortality risk in severe cirrhosis cases. ■ Serum Creatinine – with an upper limit of 4 mg/dL and an adjustment in case the patient is on dialysis at the moment of the evaluation. ■ Serum Bilirubin – a great prognostic indicator about the ability of the liver to fulfill its function. ■ INR – with the highest weight but sometimes hard to interpret in patients receiving anticoagulation therapy along due to the existence of portal vein thrombosis. The other variables remain the same as in the original Model of End Stage Liver Disease Calculator formula, including: As sodium changes in cirrhosis might be due to some other factors, not necessarily related to the severity of the condition itself or the liver damage, such as diuretic use or intravenous administration of hypotonic fluids, the model should account for this in a better proportion. The only criticism received by the model concerns the fact that it doesn’t have yet enough relevant validation. Survival chances change significantly, especially in the ranges of sodium change between 120 and 135 mEq/L, when a decrease in serum sodium of one unit corresponds to a 12% increase in mortality risk in the following 3 months. Hyponatremia is in general considered a predictor of early mortality, therefore independent of the previous MELD score but now more specific and superior to the original model for patients awaiting transplant. Serum sodium is often used as a marker for the severity of a disease, especially in cirrhosis where hyponatremia indicates solute-free water retention and the indirect marker of portal hypertension during cirrhosis.

The formula used is the one below and sodium normal values are around 135 mEq/L.

The sodium addition in the model was based on the registration data from the United Network for Organ Sharing. This model evaluation is used in patients in which cirrhosis is caused by factors that are not reversible and transplant is the only solution. This MELD-Na score calculator differs from the standard MELD calculator because it uses the Na value to adapt the result and to provide a more specialized view and improves upon the MELD Score for liver cirrhosis, especially in regard to the mortality prediction. This health tool assesses the outcome in patients who need transplant or suffer from a serious liver condition such as cirrhosis and adds the serum sodium determination to the precedent equation in the Model of End Stage Liver Disease. How does this MELD Na score calculator work?
