I'm in the same boat. I'm on my way to Quest in about an hour for a pre-employment test. I took the same ATHome test you took. (the one on the left). I had a VERY faint line in the T box just like you. Supposedly this indicates a negative test no matter how faint the line. However, I took another one today and the T line was either not there (positive) or so faint I could barely see it. I showed it to 4 people. 2 people said, no way, no line. Two people said they saw the "faintest" of lines. So I dunno. I'm drinking water and G4 and hoping that will get me by. I'm assuming I'm right on the borderline. I'm not gonna do a lot of the tricks some suggest like aspirin and niacine. I'm sensitive to these types of meds and fear a reaction. I last smoked 16 day's ago! I thought for sure that was plenty of time, but I'm old and fat these day's so I guess not. 50/50 chance I'm thinking.
