Webwhen performing confirmation testing by gc/ms or lc/ms/ms, one or more specific metabolites can be identified, quantified and reported using the applicable confirmation. Webwhat methodologies does labcorp use to perform confirmation testing? The reason is that they test for a larger.

To use the cannabinoid example, our screening cutoff level for. Webwhen performing confirmation testing by gc/ms or lc/ms/ms, one or more specific metabolites can be identified, quantified and reported using the applicable confirmation. Gas chromatography/mass spectrometry (gc/ms) and liquid chromatography with tandem. Cutoff levels are the detection thresholds for compounds that are set on the testing instrumentation. If the employer requests only on positive screening we always confirm with gc/ms.
