LRP4-IgG detection in suspected MG is rare and inconsistent across assays, suggesting that routine testing is not currently warranted and that these antibodies are at present of limited diagnostic value. These findings highlight the need for standardized, validated LRP4-IgG assays. Future studies should focus on direct comparison and harmonization of testing protocols to clarify the clinical utility of LRP4-IgG testing.
