With DOT testing, there are regulations and protocols that must be followed by the collectors.

Collectors are not going to risk this by asking for only 5 ml of sample.
Yeah you guys must be right, I'm awful with decimal measurements but I know for sure I brought in a 4oz flask and wound up only needing a fraction of it.

Indeed 5ml is tiny, I stand corrected

Probably was 45 ml then. Which means I need to get new test tubes



I suck at math, probably why I drive for a living

The rest of the post should be accurate though
