Drug and alcohol testing built for Colorado workplaces

Pre-employment, DOT, post-incident, and random testing at four Denver-metro clinics or at your site. Same-day negatives, MRO-verified positives, and a protocol written around your policy, not a menu.

Not sure which test?

Start with the situation

The reason for the test decides the panel, where it happens, and how fast the result comes back. Pick the one that fits.

Recommended

Pre-employment drug test, usually THC-free

Most Colorado employers hire on a 4-panel without THC and keep larger panels for incidents. The candidate walks in with ID and your authorization; a negative is reported the same day.

How it works

From authorization to verified result

Chain of custody at every step. Employers receive a result, never a medical record.

  1. Before arrival

    Employer authorizes

    HR or a supervisor sends the employee with the reason for test. The clinic pulls the matching panel from your protocol.

  2. In clinic or on-site

    Collection

    ID check, secured restroom, temperature check, and a sealed chain-of-custody form signed by the donor. Breath alcohol is final on the spot.

  3. Same day

    Rapid screen

    Instant-cup immunoassay read in clinic. All negative: reported to your contact today. DOT specimens go straight to the lab.

  4. Days 3–10

    Confirmation and MRO

    Any non-negative is confirmed at a certified lab and reviewed by a Medical Review Officer, who verifies prescriptions with the employee first.

What we test for

Panels from 4 to 10 substances, THC optional

Every panel shares a core of methamphetamine, opiates, cocaine, and PCP. Larger panels add amphetamines, prescription sedatives, oxycodone, and methadone. Breath alcohol is a separate evidential test with a result on the spot.

Since Colorado legalized marijuana, many employers hire on a THC-free panel and reserve THC for safety-sensitive roles and incidents. DOT drivers are the exception: THC is always required.

Compare every panel and build a protocol
PanelScreens for

4-panel (THC-free)

Methamphetamine, opiates, cocaine, PCP. The most common hiring panel for Colorado employers.

5-panel

Adds THC. Matches the traditional federal five; required composition for DOT drivers.

9-panel

Adds amphetamines, barbiturates, benzodiazepines, and oxycodone.

10-panel

9-panel plus methadone. Typical for post-accident and reasonable-suspicion protocols.

Breath alcohol

Evidential breath test, result on the spot. Add to any panel or run alone.

A urine screen shows that a substance was used at some point, not that someone is impaired at work. Prescriptions are verified confidentially by the MRO before any result reaches the employer.

For employers

Set up an account and send people in the same week

We record each reason for test, its panel, THC choice, and alcohol rule under your account. Direct billing, a single results contact, and random-pool or consortium management when you need it.

Results

Who sees what, and when

A non-negative rapid screen is never reported as a positive until a certified lab confirms it and the Medical Review Officer has spoken with the employee.

Employee

  • Copy of the chain-of-custody form
  • A call from the MRO before any non-negative is verified

  • No prescription or diagnosis detail

Common questions

Drug and alcohol testing, answered

Answers from our collectors and clinicians. General information, not medical or legal advice.

Do employees need an appointment?

No. Walk in Monday–Friday, 7 a.m.–5 p.m. at any of the four clinics. Post-accident and random tests must happen promptly, so send the employee as soon as they are notified. Booking guarantees a time if someone is between shifts or routes.

Can we test without THC?

Yes. Our 4-panel is the common THC-free hiring test, and THC can be removed from the 9- or 10-panel as well. The exception is DOT-regulated drivers, where THC is required by federal rule.

How fast are results?

When every substance screens negative on the rapid cup, the employer has the result the same day. A non-negative goes to a certified lab for confirmation and MRO review, which typically takes 3–10 business days. DOT tests skip the rapid step: negatives in 1–2 business days.

What is the difference between DOT and non-DOT testing?

DOT-regulated employees are tested under 49 CFR Part 40: a fixed federal 5-panel with THC, lab-based, MRO-verified, with results reported to your Designated Employer Representative. Everyone else follows the protocol you set. Most employers with a mixed workforce run both under one account.

Can you collect at our jobsite?

Yes. Post-incident on-site collection is available for employer accounts, including breath alcohol, and we can collect random or group events on-site for larger crews.

What does the employer actually receive?

A result, not a medical record: negative, positive, refusal, or cancelled, with the panel and reason for test. Prescriptions are verified confidentially by the MRO and never appear on the report.

Do we have to have a written policy?

Colorado does not mandate one for private non-DOT employers, but a written policy protects you in disputes and is required by many insurers and contracts. We will review a draft with you at no charge. General information, not legal advice.
