For what it's worth....

Dug through her packet of info and came across a section about the testing It said that "Body Specimen" will be:

Urine will be used for the initial test for all drugs except alcohol. Blood will be used as the initial and confirmation test for alcohol...."


Interesting. It also listed the 5 drugs the pre-employment/DOT test would test for and what the levels were. Seemed rather standard, with THC being 50ng/mL Initial Cut-off and 15ng/mL for Confirmation cut-off.
