The modified Maddrey's discriminant function) was originally described by Maddrey and Boitnott[1] to predict prognosis in alcoholic hepatitis. It is calculated by a simple formula:

(4.6 x (PT test - control))+ S.Bilirubin in mg/dl

Prospective studies have shown that, it is useful in predicting short term prognosis especially mortality within 30 days.[2] A value more than 32 implies poor outcome with one month mortality ranging between 35% to 45%.[3]

To calculate Maddrey discriminant function using SI units - micromol/l (i.e. not US) divide bilirubin value by 17.
