Explore Drug Testing Options at Fastest Labs

Our most popular drug testing methods include:

  • Hair Tests: Testing hair follicles is a noninvasive and efficient method. You can expect results fast (within one to three days). A hair sample can show drug abuse for up to three months.
  • Urine Tests: Urine can reveal a wide range of illegal substances, making it the preferred testing method for federal courts. From a urine sample, we can detect cocaine, marijuana, methadone, amphetamines, methamphetamines, barbiturates, PCP, etc. Preliminary results usually appear in minutes, but official verification can take a few days.
  • Cuticle Tests: Also known as fingernail tests, this method can detect drug use that occurred up to 8 months before the test.
  • Sweat/Skin Tests: Sweat-based tests are often administered to individuals on probation, including those with a history of addiction. This test involves actively monitoring drug use by applying a patch.
  • Saliva Tests: A quick and convenient method for detecting recent drug use. Saliva testing is noninvasive, can be performed on-site, and provides near-instant results. It’s ideal for workplace drug screenings or situations where comfort and privacy are important, detecting substances such as marijuana, cocaine, opiates, and more.
  • Panel Drug Tests: Includes 5-panel, 10-panel, and 12-panel tests that screen for multiple substances at once (all the way up to 22 panels for unique circumstances). Panels are typically conducted using urine samples and are ideal workplace, legal, or personal drug screenings. All tests are done confidentially and provide accurate, timely results.

Frequently Asked Questions About Drug Testing in Denver

Why Is Workplace Drug Testing Important?

Workplace drug testing helps maintain a safe, productive environment by deterring substance abuse and reducing accidents, especially in high-risk industries like construction. It also supports legal compliance and promotes a healthier, more accountable workforce.

Are There Specific Industry Requirements for Drug Testing in Denver?

Yes, industries like healthcare, transportation, and law enforcement often face stricter drug testing rules. Federal agencies like the DOT require specific testing protocols for safety-sensitive roles.

Employers in and around Denver often combine these federal rules with internal policies that reflect their unique operations, such as shift work, remote crews, or safety-sensitive tasks. If you are unsure which testing schedule or method best supports your compliance needs, we can explain common approaches that similar businesses in Colorado use, so you can make an informed decision. This guidance is especially helpful for newer companies that are putting policies in place for the first time or updating outdated procedures.

How Can Employees Prepare for a Drug Test?

Employees should understand their company’s drug testing policies, the type of test being administered, and confidentiality protections. Being informed helps reduce anxiety and ensures compliance with workplace requirements.

It also helps to plan your visit so that you arrive a few minutes early, bring any required identification or paperwork, and allow enough time to complete the check-in and collection process without feeling rushed. If you are driving in from nearby communities in the Denver area, make sure you account for traffic, parking, and any instructions your employer or referring agency provided. Knowing what to expect at the collection site can make the experience more comfortable and help the appointment go smoothly from start to finish.
