how does gc/ms thc testing work

[juliano67]

If the cut off for GC/ms testing is 15ng/ml, then if I'm at 10 ng/ml will they be able to see I'm at 10ng/ml
But because its below the cutoff line I'll pass, or they just won't see it at all?

If the sample registers below 15 ng, its ruled a negative. No quantitative value is provided.

If the sample registers above 15 ng, its ruled a positive and a quantitative value is provided to support the ruling.

What if its a hospital that's doing the GC/ms testing and they don't have a cut off level?
If my THC cooh urine content is at 0.02416992 will they be able to see that? Or because its at 0.02416992
They won't be able to see it because its at zero point zero ,or can they see the rest of the numbers?
Please help if you know what you're talking about

ALL urine drug tests have some sort of cutoff level. Like I said earlier, if a sample registers below that cutoff level, its ruled a negative - plain sweet and simple - on to the next urine specimen..

They are not going to worry about quantitative values on negative samples, so why should you?
