Labcorp Standard Gcms Confirmation Cut Off Levelabout - The cut off for marijuana on the screen is 50 ng/ml, which is a composite of all 31 metabolite concentrations. If the sample is below this level the test is over as a passing status. 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. 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. 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 confirm the cutoff. And how does the validation process work? What is the cutoff for quest for thc testing in the panel testing? You canโt control the lab to have a higher cutoff level. If the lab said it was 20/15 then itโs that way. But if this is a test you did on. 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. 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. Labcorp encourages the use of an independent medical review officer (mro) to review all nonnegative test results. The following are to be used as general guidelines only. 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. I work in the lab, our cut off range for urine drug screens is 36. 15 is only if you test positive, we will send it for mass spec confirmation. If you do a dip stick urine test or the ones in the cup. What methodologies does labcorp use to perform confirmation testing?
