Labcorp Standard Gcms Confirmation Cut Off Level - They can test for 50ng, but for confirmation and standard , they will test at 15ng. Which is basically nothing, but still cause for concerns. Iโm in the same. A confirmation test is required if the drug metabolite level is tested above the initial screening cutoff level. 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.
