What is the cutoff for quest for thc testing in the panel testing?
When the lab performs the screening testing, if the specimen tests below the cut off level for screening, the lab reports the test result as negative. We do not promote drug use; What methodologies does labcorp use to perform confirmation testing? When 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 cutoff for a positive.
Can anyone who’s taken a test at these. All of that to say, while it is important to remember that there is a higher. The gas chromatography/mass spectrometry (gc/ms) cut off levels are designed to rule our claims of second hand smoke or potential false positives due to over the counter. If the sample is below this level the test is over as a passing status.
