A lesson from persistently elevated aspartate transaminases (AST) in a patient with severe haemophilia A

Summary. Prior to the availability of test for hepatitis ‘C’ in 1989, any elevated AST in a pooled blood product recipient was presumed to be from non-A–non-B hepatitis. We report a patient who received pooled factor VIII in 1984 and had persistently elevated AST which proved to be of nonhepatic origin.
