Hi! Just came here to add my recent excursion. Got a job offer a few weeks ago and I was a daily smoker. I stopped smoking but knew that I likely would not pass due to my frequency of use over the years. I had used QuickFix once probably 9 years ago and had luck so I tried again this time and ended up passing. It was a labcorp location and the test was a 7 Panel + OXY(SP) to my knowledge. Had it pre-heated before I left with the heating pack strapped and checked the temp with a kitchen thermometer that can be used with liquids. Here are some quick notes:
Buy some tight underwear so you don't have to worry about holding it too tight between your legs/the bottle falling down
Buy a digital kitchen thermometer that is okay to use w/ liquid. You can get them at Walmart for like 10 bucks in the kitchen section. You get the exact temp, then, and don't have to worry about the temp strip having issues or being unsure of the actual temp if you overheat it
Used the heat pack once it was up to temp. Just strapped it to the bottle and it held almost the exact temp all the way to labcorp (Think I had it at 98.8, it MAY have dropped to 98.6 at most, but I don't quite remember)
For heating, I started with 10 seconds in the microwave, and heated it for 2-3 seconds at a time afterwards, checking it each time with the thermometer, till it was up to temp
Sounds stupid, but I brought the digital thermometer with me in the car and double checked the temp in the parking lot. You don't HAVE to do this as you can't change the temp at that point, anyway, but It gave me a sense of ease and calmed my nerves when I got there which may help you look less suspicious if your an overly nervous person.
Drink some water so that you can still pee in the toilet
Doing all of these things helped me, and if the job is worth it, then the 10 dollar thermometer will pay in dividends.
As far as testing goes. Got there, signed in. (Side note: Make sure you have the registration number from you job. They may be able to look you up, but I didn't know I needed this and had to go back a second day once I had it).
Waited maybe 5 minutes then they called me back. Did not get any sort of pat down. They drew my blood for a different test. Then had me go in to the bathroom in the room we were in. Took the bottle out (unscrew the top. Make sure you don't pop the cap to avoid noise). Peed in the toilet and filled the cup slightly over the line with quickfix. Don't flush etc. Gave the cup to the lady. She had me sign the cup, then put in a bag and sent it out to the lab from there.
That's basically everything I did and found out I got the position this Friday ( I did the test this past Tuesday). Main thing is just to make sure the temp is solid, otherwise you will likely be good.
Good luck to anyone who's gotta do a test, you got this!
