Drug Testing in Houston, Texas

With nearly 200 drug and alcohol testing centers across the city of Houston, TX, US Drug Test Centers is never more than a short drive away. Keep reading to learn more about how our drug test centers can help both individuals and businesses in Houston, Texas avoid dangerous substances and illegal drugs

What Types of Drug Tests Do We Offer?

Houston, Texas buildings at night

There are various testing methods for screening for the presence of illegal drugs. These include:

  • Urine drug testing
  • Hair drug testing
  • EtG alcohol testing/breath alcohol testing
Which of the Testing Methods Should You Choose?

It depends on what you need! Many employers opt for a simple urine drug test to keep the workplace free of harmful substances. The urine drug test is quick to conduct and non-invasive.

However, a hair drug test has a few benefits over the standard urine drug test. It's harder to tamper with, and it also offers a longer look-back period than a urine drug test. Basically, this means that we can screen for drugs further into the past.

This is helpful if you need to find any patterns of consistent drug use over time.

Making Drug Testing in Houston, TX as Convenient as Possible

While many people order their test online and visit a drug screening center within the following days, US Drug Test Centers can also offer same-day service. We do this with instant drug testing (POCT) and our on-site mobile drug testing service.

With instant drug testing, negative drug test results are delivered to you the same day. This drug testing is conducted at the same facility where you provide a specimen sample.

With our mobile drug testing service, our certified collectors can come to you within two hours of requesting your drug test. This is especially helpful for reasonable suspicion drug testing and post-accident drug testing on employees.

What Drugs Can We Screen For?

If you're looking for drug testing in Houston, Texas, you might be wondering, "What drugs can they even detect?"

The answer is: a lot!

We offer a number of individual drug tests and drug panels that screen for a wide variety of substances, including:

Cannabis plant

  • Marijuana
  • Amphetamines/methamphetamines
  • PCP
  • Cocaine
  • Alcohol
  • Barbiturates
  • Steroids
  • Suboxone
  • Crystal meth
  • Opiates/opioids
  • Toxic heavy metals

We can even test for unknown substances if you think you've been poisoned but you don't know what you consumed.

If you don't see the drug test panel you want, simply contact us to learn how we can help you.

Why Order a Drug Test?

There are several reasons why you might need to order drug testing in Houston, Texas.

Companies need to test pre-employment, with reasonable suspicion, post-accident, and before employees return to duty after an accident on the job. This is vital for maintaining a drug-free workplace.

Drug testing might also be needed for child custody cases, probation drug testing, and other types of court-ordered drug testing in Houston, TX.

Drug Abuse in the Workplace is Dangerous and Expensive

Drug testing is a very necessary part of running a business in Houston, TX.

Drug use in the workplace decreases productivity, increases on-the-job crimes and accidents, and contributes to a higher turnover rate for employees. So, it's terrible for your bottom line.

Furthermore, as an employer, you need to know that drug and alcohol use in your Texas-based company can hurt morale and job satisfaction.

By making drug and alcohol tests part of a wider drug-free workplace program, you protect yourself, the people who work for and with you, and the business entity as a whole.

3 Things to Look for in Drug Testing Centers in Houston, Texas

If you live in the city of Houston, Texas area and you're trying to find a reputable and qualified drug and alcohol testing center, here are a few things you should look for:


  • Reviews by a medical review officer (MRO): A medical review officer verifies that the drug test results are accurate. This is especially important considering that certain prescription drugs can trigger a false-positive result. The medical review officer confirms that the drug test results are a true representation of whether or not the individual consumed any illegal drugs.
  • Partnerships with SAMHSA-certified labs: SAMHSA holds labs to incredibly high standards. If a drug test company in Houston, TX works only with SAMHSA-certified labs, then you can trust that the labs' (and thus, the testing centers') drug and alcohol testing meets high expectations in terms of how accurate and trustworthy they are.
  • Robust service and support beyond basic drug testing: Particularly if you're an employer trying to keep your company free of drugs, you're going to need help beyond drug testing services.
