The QF heat pad doesnt require a mic. Simply take it out of the wrap, shake it a few times to activate, then tape or band it to the back of the bottle. The QF bottle can be mic'd for initial heat. Keep in mind that the heat pad by itself takes about an hour to heat the QF bottle to 100F. If youre in a situation where a mic is inaccessible, you can activate the heat pad in the bathroom, walk out and say you cannot pee. There, the collector will have you sit down and drink water until youre able to "produce a sample". Play the "shy bladder" game and keep checking the bottle temp until its right on. Under DHHS regulations, a donor is allowed up to 3 hrs to be able to void a sufficient amount of sample.


Drop-in additives like the U/L additive will not work on instant-type tests because it takes 90 min to destroy the drug metabolites in the sample. In addition, labs have been detecting additives on a more frequent basis than ever before. They are detected when the sample gets flagged for excessive nitrites, high chromates, and/or an abnormal pH.

Youre better off sticking with subbing, since youre planning on sneaking something into the facility.
