Types of Drug Tests
Currently, there are five different types of drug test that are in use: blood test, urine test, saliva swab test, hair, and sweat test. Each of these tests has the same function: to detect any drug in one’s organism. Thus are mostly used to discover if an individual has a substance abuse problems, or as a screening method for an employer to check their employees.
Urine Drug Test
The urine drug test is one of the most common tests. Overall, it’s an easy and noninvasive drug testing technique, which can detect drugs that have been in use weeks before testing. However, there is a slight possibility of false positive results.
Saliva Drug Test
The saliva drug test is the cheapest drug testing technique that does not require any specific laboratory equipment. As Such, conduct testing by swabbing a q-tip over someone’s inner cheek or tongue. Even though this testing method is easy to perform, it is not the most reliable one.
Sweat Drug Test
A small but sufficient amount of drug is in a person’s sweat. Therefore, by testing one’s sweat, it is possible to detect the presence of most drugs, especially if the drug was in use in the last 24 hours.
Hair Drug Test
Drug’s metabolites tend to accumulate and remain in a person’s follicles long after drug exposure. Furthermore, this technique can be used to test a person weeks after one ingested drugs.
One of the most reliable drug tests is the blood test. Although it is more invasive than other tests, it can better detect drugs, and give more information about the drug.
