Pre-hire and random Drug testing

About Concentra Drug Tests

Many companies require job applicants to complete a drug screening before they start work. Other companies may do random drug tests. It all depends on the company’s preference, their industry, and sometimes even federal law.

What drug tests test for depends on your company and their preferences. Some companies have very strict drug testing rules or must comply with federal or state laws regarding drug testing. Other companies may prefer only to test for certain substances. Two of the most common drug tests we perform at Concentra are 5-panel drug tests and 10-panel drug tests. Results will show a positive or negative status for each class of drug.

Specimen Collection
If an employer prefers, Concentra also has the capabilities to screen for a wider panel of substances. Our centers can obtain data from a variety of samples, but the two most common types are hair tests and urine tests. Hair samples can often detect prior drug use from months ago because hair grows slowly. Urine tests are the most widely utilized screening method because samples are easy to obtain and can be tested quickly.

      Why Drug Testing is Important

      Drug testing remains an important part of the hiring and employment process for many reasons. First, it is often the best preventive measure in helping ensure the safety of a company and its employees. Drug use can increase the risk of an accident, so maintaining a drug-free workplace is important for company safety. 

      A company may also be affected by the legal requirements of drug testing in their industry. In 1988, Congress passed a law requiring any company employed in some way by the federal government to maintain a drug-free workplace. Companies regulated by the Department of Labor or Department of Transportation are required by law to drug test as well.
