What Are the Different Types of Oral Drug Tests?
The two basic types of oral drug tests are on-site tests and laboratory tests. On-site tests provide instant results in less than 10 minutes, and laboratory tests are analyzed in an off-site testing facility and can take several days to a week or more for processing. Both types of oral drug test require a specimen of saliva to be acquired from the person being tested. Oral drug testing typically is performed by two major categories of people, employers needing to verify the sobriety of their employees and parents concerned about the well-being of their children.
