Screening and confirmation testing use different methodologies. These methods require different cutoff levels. Immunoassay (screening) tests typically use higher cutoff levels than more sensitive GC-MS or LC-MS/MS confirmation tests. Screening tests detect a broader group of parent compounds, metabolites, and structurally similar substances. This broader detection range requires higher cutoff levels. When a screening [...]
