Many employers find that saliva drug testing kits are more convenient for first line drug screening than urine, as there is no need for urine collection or handling, collection can be easily observed, and can be perfomed easily onsite anywhere, without the need for toilet facilities. The results are available immediately within about 5-10 minutes, and there are fewer chain of custody implications, as the sampling can be directly observed.
Another advantage to saliva drug testing for employers is that the window of detection for saliva is generally much shorter than with urine, and so a positive result suggests that an employee is under the influence of drugs, while at work. Posive results on onsite tests should be confirmed with a laboratory urine drug test.
If toilet facillities are available, then urine drug testing may be an option. The advantage of urine drug testing is that it is generally much cheaper then saliva testing, is very easy to perfom and in the case of the E-Z drug test kits with incorporated cup, the sample can easily be sent to a lab for confirmation if positive.Drug testing kits for workplace and employers
