What biological mechanisms cause 33% false positive rate in MOG-IgG testing despite standardized assays?

OPEN

The study shows only 67% positive predictive value for MOG-IgG tests, indicating substantial false positives even with established assays. Understanding the molecular basis of these false positives is critical for improving diagnostic accuracy and preventing misdiagnosis of neuroinflammatory conditions.
