AIH is a complex diagnosis partly because there is no anatomic criterion (i.e. ‘gold’) standard. AIH scoring neatly solves this problem by defining the diagnosis. ‘Definite’ scores appear highly reliable.
We are unaware of validated management algorithms using the AIH scores.
Overlap with multiple hepatic conditions is always a concern to consider despite score findings, and ‘definite’ scores are more predictive than ‘probable’ ones.
