Whether you are an employer maintaining a safe workplace, a job seeker completing a pre-employment requirement, or an individual navigating a return-to-duty process, drug testing needs to be done right the first time.
At Immunize El Paso, we provide professional, non-DOT drug testing services for individuals and employers across the El Paso region. Our process is thorough, our handling is confidential, and our results are documented in a way that stands behind you when it matters. We have been a trusted community health resource in the Borderland for over 30 years, and we bring that same standard of care to every drug screening we administer.
What Is Non-DOT Drug Testing?
Drug testing in the United States falls into two broad categories: DOT and non-DOT.
DOT testing is federally mandated for employees in safety-sensitive transportation roles, including commercial truck and bus drivers, airline crew, railroad workers, and others regulated by agencies such as the Federal Motor Carrier Safety Administration (FMCSA) or the Federal Aviation Administration (FAA). DOT testing follows a strict federal protocol with specific procedures, forms, and certified laboratory requirements.
Non-DOT testing covers everyone else. Private employers, healthcare organizations, schools, nonprofits, and any other workplace that requires drug screening outside of a federal regulatory framework all fall under non-DOT testing. The standards are set by the employer’s own drug-free workplace policy rather than a federal agency, but that does not mean the process is any less rigorous or consequential.
If you are unsure which category applies to your situation, call us at (915) 533-3414, and we will help you determine the right approach.

Frequently Asked Questions
What substances does a standard drug screen test for?
A standard non-DOT drug screen typically tests for a panel of commonly abused substances. The specific substances included depend on the panel that has been selected or requested. Common panels test for marijuana, cocaine, amphetamines, opiates, and phencyclidine (PCP), among others. Contact us or your employer for specifics on the panel being used.
How long does it take to receive results?
Most negative results are available within 24 to 72 hours. If a result requires review by a Medical Review Officer (MRO), additional time may be needed before a final result is reported. This may be the case for a positive result that needs to be evaluated in the context of a legitimate prescription.
What is chain of custody, and why does it matter?
Chain of custody is the documented process by which a drug test sample is collected, labeled, sealed, transferred, and analyzed. It creates an unbroken record of who handled the sample at every step, ensuring that results can be traced back to a specific individual and cannot be successfully challenged on the grounds of mishandling or contamination.
What if I am taking a prescription medication that might affect my results?
If you have a legitimate prescription for a substance that may appear in a drug screen, you will have an opportunity to disclose this to the Medical Review Officer if your result is non-negative. The MRO will take your prescription into account when issuing a final result. You are not required to disclose prescription information before the test.
Can individuals request a drug test without an employer ordering it?
Yes. Individuals can request a drug test for personal reasons, such as confirming their own status before applying for a job. Call us to discuss options and pricing.
