Key Points

This research aims to evaluate the effectiveness of luciferase immunoprecipitation systems in detecting myositis-specific autoantibodies compared to traditional methods.
Utilized luciferase immunoprecipitation systems (LIPS) for autoantibody detection.
Conducted comparisons with line blot and conventional immunoprecipitation (IP).
Analyzed performance across different antibody titers.
LIPS showed strong concordance with conventional immunoprecipitation methods.
LIPS outperformed line blot, especially at low to intermediate autoantibody titers.
LIPS reduced misclassification rates, improving diagnostic accuracy in myositis.

Implication

Comparative study demonstrates enhanced detection of autoantibodies in myositis patients, suggesting improved diagnostic accuracy.

Abstract

LIPS provides quantitative discrimination, strong concordance with IP, and improved performance compared with line blot, particularly at low to intermediate titers. By reducing misclassification and complementing antibody-specific thresholds, LIPS has the potential to enhance clinical stratification in myositis patients.
