Interpretation of scores: An aggregate score greater than 15 prior to therapy constitutes a definite diagnosis of AIH. A score of 10-15 is interpreted as probable AIH. A score greater than 17 following therapy is considered positive, and a score of 12-17 after therapy is considered probable, for the diagnosis of AIH.
