Any help would be greatly appreciated.
Kind of hard to answer but I imagine you could atleast cut the ng levels in half. Normally the lab can only say pass or fail, not what the levels are.
A standard immunassay test has 50ng cutoff for thc. And it doesn't test for exact levels just pass or fail. If it failes then it moves on to GC/MS which will define exactly what the substance is and at what level.
