So I had my first ever pre-emp test today, unobserved. I subbed and stashed the bottle in the taint region. It was a 45min ride up (god damn traffic). About half way there I pulled the bottle out and checked, it read 96, but I had to sit in the waiting room for a fucking hour. I finally got called up, I was kind of nervouse. I went into the bathroom took the bottle out (flip top) and like an idiot started squeezing away, it didnt make too much noise though. When the sample went into the cup it only read 90-91 but then rose to probly 93. She put some in a tube, I initialed and dated the tube and some papers and left. As I was walking away she was looking at the remainder in the cup. So heres a few questions:

1. If they suspected something wrong right there would they have said something directly to me or just sent it off with some note of suspicion?

2. How thorough are these pre-employment tests if most employers are just covering they're own asses? BTW my test was non-DOT and for an apartment maintenance job

4. I wore jeans no undies ( I find it more comfy so dont laugh) could sitting around for an hour have screwed the temp?

3. How long does it usually take for results and or an employer to call you back?

Thanx in advance,
