With increased usage of illegal drugs in the United States, it has become necessary to detect and prevent the drug users from addiction. Drug testing is the process of detecting the presence of drug from the individual's biological system. These tests are classified into different types based on the type of sample taken from the suspect. They include urine, saliva, hair, and blood tests. Saliva drug testing detects traces of the drug present in saliva of an individual. Here are some facts to be known about saliva testing. drug testing
Where is it used?
Saliva drug testing is used most commonly at workplaces and homes. Substance abuse at workplaces leads to many negative effects both for the employee and the employer. Generally, employers use saliva tests to detect drug abusing employees as they are non-invasive and can be done on-site also. Employers conduct saliva tests at different situations such as before employing a candidate and after an accident at workplace. They also conduct these tests on a regular basis and sometimes randomly.
This test is also used by parents at home to check if their teens are addicted to illegal drugs. Most parents prefer this test because the children will have no chance to adulterate the sample.
Most recent drug abuse can be detected by a saliva test. So it is performed at the time of accidents to know whether the accident had occurred due to the effect of drug abuse. It is an effective way to find drug-abusing drivers. These tests are also be conducted by courts on detainees to find if they are under the influence of drugs during crime.
How is it used?
Saliva drug test is very easy to use. A swab is placed between the gums and the lower cheek of the person for two minutes. Most of the saliva drug test kits use immunoassays for detecting the drug. When the level of drug present in the sample is below the cut-off concentration, the binding sites of the specific antibody are not saturated. Therefore a reaction occurs between the drug-protein conjugate and the kit shows a visible colored line. When the drug levels in the sample are above cut-off levels, then the antibodies get saturated and no colored line is seen. Thus the occurrence of a colored line indicates no drug abuse and absence of colored line in the kit indicates drug abuse. One can easily notice and understand the result from saliva test kits.
