Cross-reactivity in immunoassay drug screeningUnderstanding cross-reactivity performance data

A new educational video provides a basic overview of:

  • Antibody structure (cutoffs, presumptive positive, positive, negative)
  • How antibody-based immunoassays are used in the detection of drugs and their metabolites
  • Common cross-reactivity terms/definitions
  • How cross-reactivity performance data may be used to assist in test result interpretation
