 Webinar Description:

Matrix interference refers to any factor in the sample matrix – ie, serum, plasma, CSF – that can cause an inaccurate result. Matrix interference is among the most common causes of failed validations and anomalous sample data when using ligand-binding assays. These matrix effects may be caused by non-specific, drug-specific or disease state-specific factors. In this session we will discuss the possible causes of matrix interference, the impact on assay performance, methods of evaluating matrix effects, and potential approaches to resolve or avoid matrix interference.

 

Learning Objectives:

 

  • Sources of matrix interference in immunoassays
  • Types of matrix interference
  • How to identify matrix interference with assay performance
  • Techniques to mitigate the effects of matrix interference
