BOOM!...That was the nuke being dropped on the little "anxiety terrorists" that have been wreaking havoc on my emotions all week. I got the call today from my employer with a start date, PASSED!!! QF is awesome and a lifesaver, needless to say I'd be dead in the water without it. Very easy to use and EXTREMELY reliable for pre-employment testing. As long as you have an up to date batch, you are golden...golden like urine.

Couple of final notes:

*** The BATCH NUMBER is located on the instruction sheet included with your QF, in the upper left corner, it should read something like FC5-10. Call Spectrum Labs using the number provided on the instructions (upper right hand corner) to ALWAYS double check and see if your batch is current and not counterfeit.

*** The FORMULA NUMBER can be seen on the bottom of your QF box where the bar code is located. Formula 5.7 is the most current.

Thanks to everyone who posted their success stories and methods used as well as general information regarding QF. This entire thread was very helpful!
