[Guillain-Barré Syndrome: The Benefits of Autoantibodies in Daily Practice].

ABSTRACT

A huge number of autoantibodies are detected during the clinical encounter of Guillain-Barré syndrome (GBS) and its variants. The autoantibodies sensitivity and specificity are not always sufficient, especially in demyelinating GBS, where they have not yet been identified in most cases. Autoantibody results may mislead the diagnosis if the limitations of the test are not understood. Therefore, if there is any doubt about the interpretation of the results, clinicians should be careful in accurately understanding them by making inquiries to specialists.
