Background: Primary biliary cholangitis (PBC), autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) are autoimmune liver diseases associated with distinct autoantibodies. Diagnosis is based upon clinical, serological, and histopathology findings. The role of autoantibodies in the diagnosis of these autoimmune liver diseases, with the focus on PBC and AIH, will be discussed.Content: When AIH or PBC is suspected, testing for multiple autoantibodies can be requested. In this mini-review, the different ways in which autoantibodies can be tested (indirect immunofluorescence and antigen-specific tests) in the context of PBC and AIH are discussed, as well as the pitfalls in interpreting the test results.Summary: For appropriate interpretation of test results, an important prerequisite is that the doctor knows which test is used in the laboratory of choice and that the laboratory specialist is aware of what the doctor wants to test for. Good communication between clinician and laboratory specialist can, therefore, aid in the diagnosis of autoimmune liver diseases.
