Types of Drug Testing


 Ever wondered which types of drug testing program is right for your Georgia business? Georgia On-Site Labs offers all three types of drug screens throughout Georgia.



Employers across the state of Georgia and elsewhere in the country, continue to do drug testing which tests for the five most commonly abused categories of drugs including prescription drugs and marijuana. If an employee tests positive on a drug test, it is up to the employer to deal with the problem. The employer has the right to immediately fire the employee or to warn the employee that breaking the company’s drug free policy will not be tolerated. In this case, the employee may be tested again at a later date. It is a second chance for the worker to provide a urine sample free from the evidence of marijuana use. In states where medical marijuana is legal, employees are usually treated the same as a worker who is using marijuana illegally. Even with a medical recommendation from a physician, employees can be fired.

What types of drug testing should you utilize?

Did you know that there are three different types of drug screening? Here are some basic facts about the three different kinds.

Urine Tests, Hair Analysis tests and Blood tests.

A Urine Drug Test

…is by far the most common type of drug testing. Marijuana has been known to stay in one’s system for days or even weeks in high enough amounts to produce a positive urinalysis. The interesting thing here is that a positive drug test may therefore mean that the person is not under the influence of marijuana currently, and hasn’t been under it for days.urine drug test
