Home drug test kits come in four types: urine, saliva, hair follicle, and sweat. Urine and saliva tests are easy to use and provide quick results, while hair follicle tests are more accurate and detect drug use up to 90 days prior. Sweat tests are less common and considered unreliable.
There are four basic types of home drug test kits. The various kits test urine, saliva, hair follicles or sweat for the presence of drugs. These kits can be purchased online or at most drugstores, convenience stores, or grocery stores.
Home urinalysis kits are preferred by many because they are accurate, easy to use, and affordable, and provide results relatively quickly. These types of tests can detect about 10 different drugs in a person’s system at any given time. The disadvantage of urine drug test kits is that it can be contaminated easily and its ability to detect the presence of drugs decreases over time.
Another type of home drug test kit is one that uses saliva; these tests are sometimes called oral drug tests. Saliva testing kits are useful for detecting drug use that has occurred very recently, usually within a day or two. Many people also like them because, just like urine tests, they’re easy to use, convenient, and accurate, and provide almost instant results. It’s also harder for someone to manipulate the test because it can be administered directly by another person, such as a parent. It is important to remember that saliva home drug test kits are only useful for detecting very recent drug use and will not detect use that occurred more than two or three days before the test.
Hair follicle testing is another way to test a person for drug use. This type of test is usually more expensive than urine and saliva tests, but it is very accurate and much more difficult to manipulate. After the hair sample has been collected, it is sent to a lab for testing. Drug use that occurred 90 days or more before testing can be detected using hair follicle testing. This type of test needs to be sent to a lab, so the results aren’t instantaneous.
While not as common as the aforementioned home drug test kits, the sweat test is another type of drug test. A special patch is attached to a person’s skin and collects the necessary data over a period of one to two weeks. The patch has measures in place to prevent it from being removed and replaced without the tester’s knowledge. After the patch has been removed, it is sent to a lab which processes the results. This type of test is considered by some people to be unreliable and very intrusive.
