Simple scheduling, clear collection steps, and results released only to authorized parties.

1

Request Testing

Bring a current government-issued ID so the collection can be properly documented.

Employer Authorization

If your employer sent a donor pass, authorization form, or company instructions, bring them with you.

FAQ

Questions, Answered.

Negative results are typically reported within 24–48 hours. Non-negative results take a bit longer because they're reviewed by a Medical Review Officer (MRO) before being released — usually 2–4 business days.

Appointments are recommended. Same-day appointments are often available, and mobile or after-hours needs can be requested by phone.

DOT tests follow 49 CFR Part 40 procedures and use a federal chain of custody form — required for safety-sensitive transportation employees. Non-DOT tests are used by private employers under company policy, allowing more flexibility on panels and cutoffs.

Yes. We come to job sites, fleet yards, and offices for post-accident response, large-group testing, and reasonable-suspicion calls.
