AChR antibody titers should be considered in AChR antibody-positive OMG patients. Those with AChR antibody titers ≥8.11 nmol/L, who are at a greater risk of conversion to GMG, should be closely monitored and encouraged to be aware of early clinical signs of life-threatening GMG. In addition, serum thyroid autoimmune antibodies and thoracic CT screening for thymoma should be performed in AChR antibody-positive OMG patients, particularly in those with AChR antibody titers ≥2.81 nmol/L and ≥15.12 nmol/L, respectively.
