If anyone was curious I passed! Ended up having some complications and needed to take a second drug test but it wasn't because I was positive or anything the first time through.

@nexium sorry to get back to you late, hopefully everything went well but if anyone else was looking for an answer to @nexius question...
1) the labcorp dude took the cup and sharpied a line about 3/4 inches up the cup and told me to fill it up to at least there, 2 oz should be plenty.
2) practice practice practice. i know everyone says it but it's the only way to nail the right temp. i did a run through sitting with the shampoo bottle in my crotch for 45 minutes and read the temperature as 96 F. perfect. be careful with hand/toe warmers, some hand warmers are designed to get up to 130 F, while others are set to be right at 100 F. They all say on the back so just check that before you buy any. i wouldn't risk bringing in any extra equipment (thermometer) to the collection room..i guess you just have to have faith in the temperature at that point. one other thing i want to note is that at least at the location i did mine at, the guy printed out the summary of my sample BEFORE HAND. I noticed that the box on the form that asked "Sample between 90-100 F?" was already filled out with a clear "YES". So basically you are innocent until proven guilty :P.
3) the thermometer is definitely worth it. who cares how much money you have to spend to acquire the job? you'll be able to make it back if/WHEN you pass the test!! i can't speak for the quick fix or it's reliability. but as for the location of the shampoo bottle, just use boxer briefs or compression shorts and secure it right on tha gooch.

good luck everybody
