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 medical testing center. This is normally a sample of urine, blood, or hair, though saliva may also be used in some cases. After collection from the donor, the sample is sealed with a tamper-evident seal and 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. Cost may also favor this test when there are a significant number of samples to be tested.
