Oral drug testing will never replace urine drug testing or hair drug tests because each type of test gives you different information. Hair testing detects drug use over a period of months, urine testing detects drug use for a period of days and saliva drug tests measure a drug history in hours. For monitoring abstinence, urine drug testing is still the most reliable method of testing, but sometimes oral fluid drug testing can provide an excellent backup - especially if toilet facilities are unavailable.
It is becoming increasingly common for employers and the courts to ask for a Hair Drug Test. Testing for illegal substances in hair gives you a greater time frame of detection than urine, blood and saliva. In fact, you can often detect drugs in hair for several months - if not years, if the hair is long enough. The most common request we have for hair testing is a 3 month or 90 day history of drug use or abstinence, requiring a 3 cm (1 ¼ inches) length of hair sample.
Urine testsUrine tests are the most commonly used drug test and will detect drug use in a period of days, same sex testers and suitable facilities will be required.
