Thc Drug Test
UpdatedHi, I had marijuana over a 3 day period then got selected for a random drug test at work 3 days after I did that. I also have a valid script for oxycodone, so that doesn't worry me. They did an 8 panel test, and she said it was getting sent for further testing. I know I failed the opiates, like I said I'm not worried about that. I can provide a valid prescription. I came home the next day and took an at home thc drug test and it came back negative. Does anyone think I still could have failed?

There's a cut off level if it's low enough it would be labeled a negative for the bud.
Re: Dash (# 1)
I learned from a lab supervisor that these cut off levels on a SAMHSA or NIDA drug test the cut off levels for a simple positive THC and metabolite test is 50ng/kg. A WADA drug test assumes 150ng/kg is representative of usage such as last night or that very day. I was unable to find their rationale on this. Warning to all:. In some cases "zero tolerance" drug testing is called for where drugs are tested for and detected within the capabilities of the lab. This type of test ignores the SAMHSA recommended cut off levels.
