Don't know if you saw this but it seems you can't draw any solid conclusion from a faint line.

TChong Reviewed by TChong on . How faint is faint? Pic attached So this line cannot be photocopied, but shows up on my camera. If there is a line, no matter how faint, does it absolutely mean you are below the threshold? I finally have a confirmed drug test on the 28th, been clean for about a month. I tried diluting several times and could never get my creatinine levels high enough (Yes I waited a few days after taking supplements, read my other posts). I can't use synthetic urine because they will be watching. So have to pass naturally. Rating: 5
