Overview
This clinical study aims to evaluate the diagnostic performance of a new Epstein-Barr virus (EBV) C promoter methylation detection kit. All participants will undergo a series of diagnostic tests including VCA-IgA, EBNA1-IgA, and EBV-DNA assays. Additionally, nasopharyngeal swabs will be analyzed for EBV C promoter methylation. Confirmatory biopsy will be performed on all patients to establish a definitive diagnosis. This comprehensive approach seeks to assess the effectiveness of the methylation detection kit in a clinical setting.
