Well, I'd never ask straight up, but I thought about calling and saying it's my first drug test and I wasn't sure if it was my responsibility to follow up (I'd call the lab, not my job). The first part is actually true. Thanks for your support and advice, everyone. I guess I'm in the clear but would still like something concrete for closure. If no call tomorrow, I think I'm officially OK.

I also posted here because it seems important to keep up-to-date on QuickFix results. I scoured these forums and got lots of great advice pre-test, but I knew there were many like me that were weary if QuickFix "still works".
