Testing for drugs has become more common in recent years due to the increase in distribution, use and consumption. There are different types of testing screens available for use by both government, public and private sector employers and even for personal use by individuals. Some are considered regulated while others are not. The regulated screens are mandatory and the main one is dot, better known as the department of transportation, while everything else is referred to as a non dot drug test.
Regulated drug screens are five panel tests in which they are looking for specific substances. These substances are marijuana, cocaine, amphetamines and methamphetamines, opiates and phencyclidine. Someone undergoing a regulated drug screen must have a federal chain of custody form.
Regulated or mandated screenings are searching for the presence of amphetamines or methamphetamines, cocaine, marijuana, opiates and phencyclidine. The unregulated or unmandated screenings search for the presence of the same substances as mandated screens however they also usually include the presence of benzodiazepines, barbiturates, methadone, propoxyphene and methaqualone. Some unmandated testers have been known to increase the panels to greater than ten and include the presence of even more substances including prescribed medications.
There are different methods for detecting the presence of substances and each one varies in the detectable usage timeframe. The most common and preferred screening method is with urine samples. The results are typically available within 24 to 48 hours and can detect usage up to fourteen days prior. The samples are generally sent to a laboratory for analyzing and there are medical review officers on hand for anything that has questionable levels; however, it is possible to do an on the spot immediate uncomprehensive screening.
Hair sampling is the most comprehensive screening but in the least used. Hair screens can detect substances used up to 90 after use and the results take anywhere from 3 to 4 days to obtain. This is commonly used for court cases and accidents with fatalities.
There are also oral swab collections. A swab is used to collect samples of saliva and fluid from the mouth. This type of screen can detect the use of substances anywhere from twenty four hours to seven days out. The turnaround time is usually anywhere from twenty four to forty eight hours and similar to the urine analysis if the results are too high or too low a medical review officer will review the findings.
Blood samples can also be used to analyze for substances however believe it or not these are the least accurate because the substances clear out of the blood within hours of use and can sometimes not be detected. The most common method used is urine; however, the cleaner and easier method is the oral swab tests.
The best time to perform testing for substances whether it is a dot or non dot drug test is when the person is not expecting it, that way they cannot try and create a false negative. You want the results to be accurate and reflect the possible use or abuse of substances, especially illegal substances. It could be a matter of protecting or saving someone from harm, danger or even death.
