Yes OldMan, exactly, practice how much you need to dilute to pass right now, even if you have a little more time to clean out. Just give you more peace of mind. And it would be far better to be labeled "inconclusive" then "fail". The first void of the day is always the worst, although I know that's why you're testing it - to check the worst case scenario. But it's also not what you will submit, right?

etmrktgbrandon - I am 98% certain you are good to go if you have abstained for 80+ days. But flushing a few healthy doses of Gatorade during the 2 or so hours leading up to the test would be a little extra insurance and doubtful to be flagged as too weak a sample.

All of the tests I have seen myself plus training videos, the (T) line is never as dark as the (C) line.

I recommend general to mild dilution to anyone anytime - no harm in it. Although it certainly doesn't always mean it's the cure-all if you smoked yesterday. I prefer afternoon test samples rather than morning samples to be as far from the morning startup as possible. But whatever time period is best for you to control your intake I suppose.

Sorry, I don't know enough about QuickFix to comment on that scenario.
