5 methods of drug testing that employers use today

Drug testing before and during employment has become very common today. Throughout the years, drug testing technology has improved. Now the testing results can be accurately interpreted. Here are the best methods of drug testing available today.

Urine drug testing

It is the most common form of drug testing. Analytical methods like immunoassays, gas spectrometry, mass spectrometry and thin layer chromatography are used. These are very simple techniques of drug testing. However, it is difficult to find out the levels of drug that are present in the urine. For certain drugs, you may also get false results.

Saliva testing

It is a very popular type of drug testing. It can get accurate results if you have used drug very recently. For example, it can detect drugs that you have taken a few hours ago.

Hair testing

When drug metabolites get inside the scalp’s blood vessels, they get filtered by the hair and remains there. So, if you test hair, you can find the presence of the drug. However, this type of drug testing cannot determine the recent use of the drug. It takes a long time to do the test and it is expensive as well. So, most employers don’t prefer this method of drug testing.

Blood testing

It is a very invasive and expensive method of drug testing. It can detect the presence of drugs very accurately. You can determine the level of drug as well. But this type of testing is used less often because of the expense.

Perspiration testing

It is a new form of drug testing. A sweat patch is used to do the test that needs to be affixed to the skin for 14 days. This type of drug testing is often used when employees are on probation.

All these tests are done in the workplace to test whether employees have taken drug or not. These tests can determine the presence of illegal drugs like marijuana, cocaine, opiates, PCP, and others.
