The COVID-19 pandemic has left a lasting impact on diagnostic immunoassays, with emerging evidence linking SARS-CoV-2 infection to increased antibody-mediated immunoassay interference. This presentation explores the rise in interference, particularly from rheumatoid factor (Rf), and its implications for assay accuracy. Post-COVID immune dysregulation has led to elevated levels of autoantibodies, including polyreactive RF, which significantly increase the risk of false results in immunoassays.
Attendees will learn about:
- Mechanisms of antibody interference
- The post-COVID increase in interference challenges
- Practical strategies to mitigate interference and protect assay performance
The session will also explore the role of passive, active, and universal blockers in neutralizing interfering antibodies, highlighting Meridian Life Science’s portfolio of solutions designed to improve reliability across ELISA, CLIA, and LFA platforms.
