UNOS also operates a 24/7 electronic matching system accessible to every organ procurement organization (OPO) and transplant center in the country. The national transplant candidate waiting list for all organs is managed by the United Network for Organ Sharing (UNOS). Sodium values less than 125 mmol/L will be set to 125, and values greater than 137 mmol/L will be set to 137.In the United States, thousands of people are currently on the waiting list to receive a liver.The upper limit for serum creatinine is 4 mg/dL, therefore for those patients that have had 2 rounds of dialysis in the past week, the value is automatically adjusted to 4 mg/dL.Values less than 1 are automatically adjusted to the lower limit value of 1 to prevent obtaining a negative score.Regardless of the formula used, there are three adjustments to be made: In January 2016, OPTN changed Policy 9.1 in regard to the calculation of the MELD score to include serum sodium (measured in mEq/L and in case the patient is known hyperglicemic, sodium correction may be needed for glucose levels above 120 mg/dL). The formula resulted from the original study referenced below is: International normalized ratio time (INR).The variables used by the MELD calculator are: The MELD score assesses the severity of the chronic liver disease and is used in the liver transplant waiting list prioritization by the United Network for Organ Sharing (UNOS).
