Maryland Drug Testing

Getting tested for drugs and alcohol in the state of Maryland is more convenient than ever before. Keep scrolling to learn about how we work with employers, employees, and other individuals in Maryland to protect our communities from substance use.

Conduct Workplace Drug Testing With US Drug Test Centers

Drug testing is vital for Maryland employers, especially with marijuana legalization and our country's problems with opioid abuse. The illegal use of drugs and alcohol in the workplace can lead to an increase in crime and on-the-job accidents. It hurts morale and productivity among workers, and it increases employee turnover.

How can Maryland employers ensure their place of business stays free of drugs and alcohol? Here's how US Drug Test Centers can help:

  • We will conduct all of your workplace drug testing, including pre-employment (for prospective employees), random, reasonable suspicion, post-accident, and return-to-duty drug testing.

  • We'll train your staff — including your designated employer representative (DER) — to manage your workplace drug testing program, including how to determine reasonable suspicion.

  • US Drug Test Centers can run all of your background checks. Order them and view your results electronically.

Drug Testing in Maryland for Individuals

Drug and alcohol testing is also available for individuals. Our court-ordered drug testing services include DUI, child custody, and probation drug testing.

Why Us?

What makes us the best partner for all of your drug testing needs?

Unparalleled Accuracy

We only work with SAMHSA-certified laboratories in Maryland. This type of specially certified laboratory is held to higher standards when it comes to its drug testing processes and equipment.

Additionally, a medical review officer (MRO), who is a licensed physician, confirms the results of all drug tests. Let's say you require employees to undergo testing and one employee receives a positive test result. But they believe it was a false-positive drug test due to their prescription medication. An MRO can help validate the results.

Endless Options for Drug Testing

We can conduct our drug tests via hair, urine, and breath. Get screened for a large variety of substances, including marijuana, suboxone, cocaine, steroids, opioids, PCP, ecstasy, Rohypnol, barbiturates, and many more. We can even test for the presence of heavy metals.

You can order tests individually, or combine them into a panel. For example, our 15-panel test screens for substances including marijuana, fentanyl, methadone, and amphetamines.
