so I've been practicing dilution meathod for my drug test next Tuesday and as you may know the directions say that even a faint line is considered a negative. I have only been able to pass with a very faint line. My drug test is for probation so it's a very legit test. is the faint line pass going to pass on a quality test?? Does the darker the line mean less thc metabolite content?

Contrary to popular belief, there is no meaning attributed to intensity or width of the lines. Assay kits have no ability to quantify metabolite levels (unlike the GC/MS) - they are simply a quick go/no-go analysis. To say that a darker line means less THC metabolites would be speculating.

If a line appears in the 'T' window, even a faint one, its still a negative.

so are you saying that those tests wont really tell me if i can pass any kind of real test?

No that not what I'm saying at all. Re-read my reply.
