During a drug test, a certain sample, such as urine, hair, blood, breath, sweat, or saliva, is taken from an individual. This specimen is subjected to a test that identifies whether strains of particular drugs are present. Numerous types of drug tests can be conducted to serve various purposes. Below are the things you need to know about these drug tests.

Types of Drug Tests


  • Urine Testing


One of the most common types of drug testing involves taking a urine sample from the individual who needs to be subjected to the evaluation. This is one of the most common drug screening processes that is implemented. A urine drug test can detect a wide range of drugs including amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, methamphetamine, as well as opioids. However, some leverage screeny weeny, which is a product that aids them in passing urine drug screening since most labs fail to determine that the urine from its Push & Pee function is fake. But take note that this is not what this device is primarily designed for. Rather it is intended to fulfill a fetish and spice up things in the bedroom, or as a prop in shooting a movie.


  • Saliva Testing


Drug screening tests using the saliva of a person is slowly becoming more and more popular because of the simplicity of the process in taking the sample. While it is a non-invasive method, this test is only appropriate in determining recent drug use. Otherwise, there is a great chance that it may yield inaccurate results because it can only detect the presence of drugs which have been consumed ten hours before the test is taken.


  • Blood Testing


Screening for the presence of drugs in a person using a blood test can generate the most accurate results. It can even determine the actual amount of drugs present in the bloodstream of a person during the time that the test is taken. However, it is also the most expensive and invasive type of drug test, which is why it is infrequently utilized.


  • Hair Testing


There are research studies that show that drug compounds can enter the blood vessels in the scalp, such that the hair filters them, keeping them a permanent record of the person’s drug use. For this reason, many people object to this type of drug screening since it doesn’t reflect the current and actual drug use of a person. In addition to this, processing hair samples for drug screening also takes much time, which makes this drug screening process less favored.


  • Perspiration Testing


Screening for the presence of drugs through sweat samples is one of the newest testing methods. In this method, a person is asked to use a sweat patch that needs to be affixed on their skin for two weeks. Because of the length of time, it takes to execute this drug screening process, this is more recommended for those who are under probation and recovering from drug abuse.

Purpose of Drug Tests

Drug tests serve a variety of purposes. For one, doctors may request for a drug test in case the medical professional has an inkling that their patient is using illegal drugs or misusing their prescription. In addition to this, a rehabilitation center may also request for a drug test to evaluate whether the people they previously helped with to cope with addiction are staying sober.

Routine drug tests are also taken from time to time as mandated by the government as a requirement for certain licenses such as a driver’s license. Employers may also list a drug test as one of their onboarding requirements. In the same manner, schools and universities may request random drug testing or mandatory drug testing should they host particular sporting events.

How to Prepare for a Drug Test

In case you need to undergo a drug test for whichever purpose it may serve, make sure that you prepare for it, though there is not much preparation involved. More often than not, all you have to do is be there at the testing site on your scheduled test and provide the sample that is required of you. Make sure that you indicate all the drugs and medications that you have been taking before the test because there are some prescribed drugs, as well as health supplements, which may cause a false positive. Depending on the process in the lab, you may already have the results within a couple of hours or even sooner.


In conclusion, there are many types of drug tests which include urine, saliva, blood, hair, or perspiration testing. These tests suit various purposes and can be requested by doctors, employers, or even the government as a requirement for a particular license. In case you need to be subjected to a drug test, make sure that you perform the necessary measures to prepare for it.
