You only have to give them one sample....they split the sample after you give them your pee. Sample A is the one they actually do the test on.... Sample B they hold for up to a year in case you test positive and that is the sample that would be retested.
They are supposed to put the seals on in front of you and then you initial or sign the paperwork...trust me....there is a sample B..... I repeat....thats what they use to retest if you came up positive.


ALWAYS FORWARD.....NEVER STRAIGHT
