What is MELD PELD score?
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. A MELD score is a number that ranges from 6 to 40, based on lab tests. It ranks your degree of sickness, which shows how much you need a liver transplant.
What is a normal PELD score?
PELD was calculated by computation of bilirubin (median: 11mg/dl; range: 0.3-51.9), albumin (median: 3.8g/dl; range: 1.7-5.1), INR (median: 1.2; range: 0.9-8.0), age, and growth retardation.
How high does a PELD score go?
MELD and PELD MELD, the Model for End-Stage Liver Disease, is a numeric scale, ranging from 6 (less ill) to 40 (gravely ill). Used for transplant candidates age 12 and older. PELD, the Pediatric End-Stage Liver Disease, is a numeric scale for transplant candidates younger than 12.
How does a PELD score work?
Scores range from 6 (low level of illness) to 40 (gravely ill). For persons under the age of 12, the calculator is called PELD (Pediatric End-Stage Liver Disease). The PELD score includes age, bilirubin, albumin, INR, and history of growth failure.
How do I calculate my MELD score?
The new MELD scores are calculated first by determining the traditional MELD score as an initial score (MELD(i)); if the initial MELD(i) score is 12 or greater, the score is adjusted by incorporating the serum sodium value….3-Month Mortality Based on MELD Scores.
|MELD Score||Mortality Probability|
|9 or less||1.9% mortality|
What MELD score is considered end-stage liver disease?
A MELD score of greater than 11, or the presence of both ascites and an elevated bilirubin greater than 8 mg/dL should prompt consideration of specific therapeutic interventions to reduce mortality.
How do you calculate MELD?
MELD uses the patient’s values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival. It is calculated according to the following formula: MELD = 3.78×ln[serum bilirubin (mg/dL)] + 11.2×ln[INR] + 9.57×ln[serum creatinine (mg/dL)] + 6.43.
Does a MELD score ever go down?
A patient’s score may go up or down over time depending on the status of his or her liver disease. Most candidates will have their MELD score assessed a number of times while they are on the waiting list. This will help ensure that donated livers go to the patients in greatest need at that moment.
How do you calculate your MELD score?
Model for End-Stage Liver Disease (MELD) for ages 12 and older
- 3.78 loge Serum Bilirubin (mg/dL): +

How is MELD score calculated?
How do you read a MELD score?
The MELD score ranges from six to 40 and is based on results from several lab tests. The higher the number, the more likely you are to receive a liver from a deceased donor when an organ becomes available.
What is MELD INR score?
It is derived from the International Normalized Ratio (INR) of prothrombin time, serum creatinine, and serum total bilirubin. The major use of the MELD score is to prioritize allocation of organs for liver transplantation among patients with chronic liver disease.
What is a good MELD score for the liver?
The “normal MELD score” is based on the individual, but with a MELD score of greater than or equal to 10, you may be referred to a hepatologist, or liver specialist.
How long can you live with a MELD score of 20?
People who have a MELD score of less than 9 have a 1.9% to 3.7% risk of dying within the first three months. People who have a MELD score of 10 to 19 have a 6% to 20% risk of dying within the first three months. People who have a MELD score of 20 to 29 have a 19.6% to 45.5% risk of dying within the first three months.
How is liver MELD calculated?
How Is Your MELD Score Calculated? Your MELD score is based on results from four blood tests that, together, show how well your body is functioning. You will be tested for: INR (internal normalized ratio): Indicates whether your liver is making the proteins necessary for blood to clot.
How do you calculate MELD in Excel?
It is calculated according to the following formula: MELD = 3.78×ln[serum bilirubin (mg/dL)] + 11.2×ln[INR] + 9.57×ln[serum creatinine (mg/dL)] + 6.43.
What is a healthy MELD score?
MELD Score References The “normal MELD score” is based on the individual, but with a MELD score of greater than or equal to 10, you may be referred to a hepatologist, or liver specialist.
How is the MELD score calculated?
The MELD uses the international normalized ratio for prothrombin time (INR), the serum creatinine and serum bilirubine values in order to display the MELD Score according to the following formula: Original MELD Score = 10 * [(0.957 * ln(Creatinine)) + (0.378 * ln(Bilirubin)) + (1.12 * ln(INR))] + 6.43.
How do I determine my PELD score?
To determine your PELD score, please complete the form below. Please note that the accuracy of your score is based on the amount of information you provide. The MELD and PELD calculators are used for liver allocation in the OPTN match system.
Is it better to use the calculator or meld calculator?
It is preferable to using the calculator to calculate the MELD as there are several caveats relating to minimum and maximum values assigned in the MELD. Values should be no more than 48 hours old. MELD can be used on any patient with end stage liver disease irrespective of cirrhosis etiology.
What is the age range for the meld calculator?
This calculator is recommended for ages 12 and older. All fields are required. Had dialysis twice, or 24 hours of CVVHD, within a week prior to the serum creatinine test? Note: Creatinine will default to 4 mg/dl with a positive response. The MELD and PELD calculators are used for liver allocation in the OPTN match system.
