Drug checks appear for these metabolites, which continue to be in your physique longer than THC.

Eventually, THC and its metabolites are excreted in urine and stool.

(More specifically, THCA, a direct metabolite of THC.)

In the case of a effective test, every other pattern of the identical hair is normally put via a secondary take a look at that uses methods referred to as fuel chromatography and/or mass spectrometry. These techniques, recognised as GC/MS and GC/MS/MS (tandem MS), are extra accurate, greater worried strategies that scan the pattern for the “molecular signature” of the goal compound.

The ultimate awareness of the chemical in a pattern of hair offers the last verdict. The “confirmatory level” of THCA that Quest Diagnostics makes use of is 0.1 picograms per milligram of hair. Anything above that distinctly lots confirms you’ve used weed in the past three months.
