Although there is little doubt that the recognition of the association between the presence of ANCA and active vasculitis has had a very positive influence on research on the pathogenesis and treatment of ANCA-associated diseases (reviewed by Savage [3]), there are reasons to worry about the application of this recently gained knowledge in clinical practice. In this comment the problems with the clinical application of ANCA tests are categorized for the sake of clarity as (i) standardization problems, (ii) difficulties with application of the test in the appropriate
