This calculator implements the scoring system described in International Autoimmune Hepatitis Group Report: review of criteria for diagnosis of autoimmune hepatitis. J Hepatol. 1999 Nov;31(5):929-38. That scoring system is somewhat complex in that some features contribute to the score only in the absence of other features. For example, HLA DR3 positivity only contributes when other antibodies are negative. This calculator correctly scores such circumstances. Also, it is not possible to check off boxes in an illogical fashion.
