NotFadeAway, yes BurntToast beat me to it, but NEVER NEVER NEVER inquire about your test results!!

That's exactly how I would take it. If they never called you back to say you can't start on your start date then you should be good to go!! Being that you took the test on the 6th, I would think they would've had results yesterday or maybe today at latest, but as long as you used Quick Fix and your temp was right, you have nothing to worry about....just show up on your start date and get paid!!!
