As First Choice Drug Testing Collectors, our best weapon to thwart cheaters is not the temperature strip on the cup; it’s our “6th sense”. Over the years, we have developed an ability to sense when something is just not quite ordinary about how a donor is acting. It’s not just one thing and it’s not always the same behavior – cheaters all have different mannerisms and verbalizations that usually give them away before they even hand us their sample.
