Drug Testing
Drug Detection Service & Equipment -  Employment screening
Solano County, San Francisco North Bay, Ca. USA

Drug tests can be divided into two general groups.

 The first group is the kind most people are familiar with. This type of testing involves the donor giving a sample of some bodily fluid or hair to an employer, doctor, law enforcement official, or a dedicated testing center. This is normally a sample of urine, blood, hair, or saliva/oral fluid. After collection from the donor, the sample with a tamper-evident seal is sent to a laboratory for analysis. The primary advantages of this type of test are accuracy, legal defensibility, and the ability to customize tests for a particular demographic group. The disadvantages are typically costs associated with the need for collection sites (urine, blood), and the delay in receiving results (up to 4 days). On-site screens, done with an inexpensive kit, allow results within minutes. Furthermore, if on-site screens, such as oral or saliva tests, are used, the problem of "beating the tests" (otherwise known as sample adulteration or substitution) can be virtually eliminated. On-site screens provide qualitative results, and when supplemented with laboratory-based confirmation tests, can be defended in a court of law.
