Canadian Association of Gastroenterology Practice Guidelines: Evaluation of abnormal liver enzyme tests

Approximately one in 10 Canadians has at least one abnormal liver biochemical test on routine screening. Although in the majority of these individuals the abnormality reflects a benign liver condition such as Gilbert's syndrome or enzyme induction from recent alcohol consumption, a subgroup will have progressive and potentially life-threatening liver disease for which therapeutic interventions are often available (1). The objectives of these guidelines are to, first, outline when screening for liver disease would be appropriate; second, determine which biochemical tests should be used in screening for liver disease; third, review second-line tests for when screening tests are positive; fourth, outline when referrals to specialists would be appropriate; and, fifth, review additional testing that specialists might undertake in their evaluation of the patient.
