Accreditation in autoimmune diagnostic laboratories. A position paper of the European Autoimmunity Standardisation Initiative (EASI)

Reliable autoantibody detection is important for early diagnosis and appropriate treatment of autoimmune disorders. However, in contrast to testing for classical clinical chemistry analytes, autoantibody testing is complex and evolving. Moreover, there is a lack of standardization. Nevertheless, it is important that laboratories that provide autoimmune tests comply with the requirements set forward by general international accreditation bodies. In the present manuscript, an ad hoc committee of the European Autoimmunity Standardisation Initiative (EASI) group provides background information on accreditation and identifies the minimum requirements needed to set up an accredited autoimmunity lab and to ensure that high-quality results are provided (in terms of personnel, procedures, validation, quality control, and reporting). Areas in which additional work needs to be done are identified.
