Sweat or patch drug testing is the least popular form of employment drug testing. It requires wearing a patch for an extended period of time and may be controversial in terms of accuracy due to possibility of surface contamination. Because of the long detection time, sweat drug testing can reveal drug usage for at least 7 days and low levels of drugs from 2-5 hours after usage that other tests might miss.
