Are drug test always accurate?
Yes, but the odds are long and getting longer all the time. The science of drug testing has progressed significantly in recent years. Some of the procedures that have been instituted to determine intentional attempts at ‘beating’ a drug screen are: Chain of Custody procedures and specific protocols that track the specimen from the moment of collection through the processing and storage procedure; Temperature strips, which assure the sample temperature matches body temperature at the time the collection is made; Integrity testing, to determine Creatinine and specific gravity levels, which detect attempts to dilute the specimen; Adulterant testing, developed to identify attempts to use nitrites and other adulterants as a means to disguise drugs in the collected sample.
