в– DF = 4.6 x (prothrombin time - control time) + (bilirubin in Ојmol/L)/17.1 в– DF = 4.6 x (prothrombin time - control time) + bilirubin in mg/dL The two formulas adapted for the measurements units are: For convenience, the user can choose the measurement system either SI or US therefore can input serum bilirubin in either mg/dL or Ојmol/L в– Bilirubin вЂ“ reflecting the metabolic function of the liver, usually elevated in cases of alcoholic liver disease.

в– Control time measured in seconds вЂ“ differs based on each medical laboratory specifications and is usually between 10 and 14 seconds. Normal range is between 11 to 13.5 seconds in patients that are not under blood thinning medication such as warfarin. Also often given as the INR (international normalized ratio) result directly. в– Prothrombin time measured in seconds вЂ“ indicative of the liver function as reflected in how long it takes for blood (plasma to be exact) to clot. The three factors used by the Maddrey score for alcoholic hepatitis calculator that are used in risk stratification are explained below: This is a health tool also known as the MaddreyвЂ™s discriminant function (DF) that predicts the outcome, mortality risk in one month, in patients suffering from alcohol-related hepatitis and also identifies cases in which steroid therapy is recommended. How does this Maddrey score for alcoholic hepatitis calculator work?
