How Employer Drug Testing Works

You tell us what your company needs, a specialist scopes and prices the program, and testing gets handled from there. Here is what each of those steps actually involves.

1. You Tell Us What You Need

The form asks five questions: which kinds of testing you need, how many employees you have, where they are, how soon you need testing in place, and how to reach you. That is enough for a specialist to come to the first conversation already knowing the shape of your program.

If some of your employees are federally regulated, mention it in the notes. That testing follows 49 CFR Part 40, which has its own requirements for collections, laboratories, Medical Review Officers, and recordkeeping, and it has to be kept separate from your company program. See DOT compliance help if that applies to you.

2. A Specialist Contacts You

Within one business day. This call is about scope, not a sales pitch:

  • Which testing reasons you run. Pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up each have their own trigger and their own paperwork.
  • What you test for. Panels vary, and so does the right specimen type for your situation.
  • Where your people are. One site, many sites, or spread across states and working remotely.
  • What your policy says. If you have one, it drives everything. If you do not, that is the first gap to close.
  • Where the state rules pinch. Some states restrict random testing, require advance notice, or attach conditions to workers' compensation benefits.
  • Volume and cost. Pricing follows from all of the above, which is why nobody can quote you honestly before it.

3. Your Program Is Set Up

Once scope is agreed, setup covers the practical pieces: who your designated employer representative is and who else may receive results, how tests are ordered and employees notified, how collections happen for each group of employees, how results are delivered, and what records are kept and for how long. If you are running random testing, this is also when the selection process and pool are established.

For a multi-state employer this is where consistency is won or lost. The goal is one program that applies the same standard everywhere, adjusted only where a state requires something different.

4. Testing Happens

After that, testing runs on your triggers. A hire reaches a conditional offer and a pre-employment test is ordered. A random selection comes up. An incident happens and a post-accident test is ordered under your policy. A supervisor documents reasonable suspicion and a test follows.

Where employees are far from a collection site, or working remotely, remote collections observed over live video can be used for non-DOT testing. DOT-regulated testing follows the collection procedures the federal rule requires.

5. Results Are Confirmed and Reported

A negative result is reported to the contacts you designated. A non-negative screen goes to a laboratory for confirmation, then to a Medical Review Officer, a licensed physician who reviews the confirmed result and contacts the employee about legitimate medical explanations before any verified result reaches you.

That sequence exists to protect both sides. Employees with valid prescriptions are not reported as positive, and employers are not making employment decisions on an unverified screen.

The decision stays yours. A verified result is information. What happens next comes from your policy, your HR process, and your counsel's advice, not from your testing provider.

6. The Program Keeps Running

Ongoing work is where most of the effort actually sits: random selections on schedule, new hires added and departures removed, supervisor training kept current, records retained, and the program reviewed when you enter a new state or when a state changes its law. Marijuana laws in particular have changed often, and a policy written five years ago may no longer match what your state allows.

What We Need From You

  • Your current drug testing policy, if you have one
  • Locations and states where you employ people
  • Headcount, and which roles are safety-sensitive
  • Whether any employees are DOT-regulated, and under which agency
  • Who should receive results
  • Any deadline you are working toward

That sequence is how our employee drug testing services run from first contact through ongoing administration.

If you do not have all of it, submit the form anyway. Sorting that out is part of the conversation.

Common questions

How long does it take to get a program running?

It depends on how much already exists. An employer with a written policy in place and one location can often start testing quickly. A company building a policy from scratch, coordinating several states, or moving off another provider takes longer, because the policy and the account setup have to come first. Your specialist will give you a realistic timeline on the first call rather than an optimistic one.

What do you need from us to get started?

Your current policy if you have one, a list of locations or states, headcount, which roles are safety-sensitive or DOT-regulated, who your designated employer representative is, and how you want results delivered. If you do not have some of that, the first call is partly about sorting it out.

Can you work with the policy we already have?

Yes, and in most cases that is the better starting point. An existing policy already reflects decisions your company has made and, often, language your counsel approved. A specialist will point out places where it does not match how testing actually runs, which is where problems tend to appear later.

What happens when a result comes back non-negative?

A non-negative screen is not a positive result. The specimen goes to a laboratory for confirmation testing, and a Medical Review Officer, who is a licensed physician, reviews the confirmed result and contacts the employee to ask about legitimate medical explanations such as a valid prescription. Only after that review does a verified result go to the employer. That step protects employees with legitimate prescriptions and protects you from acting on an unverified result.

Do we still need our own HR process?

Yes. Testing tells you a result. What you do with it, such as rescinding an offer, referring someone to treatment, or ending employment, is your decision under your policy and your state's law. Specialists run testing and reporting; employment decisions stay with you and your counsel.
