This paper presents the Italian guidelines for autoantibody testing in myasthenia gravis that have been developed following a consensus process built on questionnaire-based surveys, internet contacts and discussions during dedicated workshops of the sponsoring Italian Association of Neuroimmunology (AINI). Essential clinical information on myasthenic syndromes, indications and limits of antibody testing, instructions for result interpretation and an agreed laboratory protocol (Appendix) are reported for the communicative community of neurologists and clinical pathologists.
