What does building a drug-testing program involve?
A defensible workplace drug-testing program has eight working parts: (1) policy, (2) panel, (3) specimen, (4) collection site/vendor, (5) laboratory, (6) MRO, (7) training (supervisors, designated employer reps), and (8) records and program management. DOT-regulated employers add a return-to-duty / Substance Abuse Professional (SAP) process and (for FMCSA) clearinghouse reporting.
1. Written policy
A written policy is the foundation. It defines who is covered, what tests trigger testing (pre-employment, random, reasonable suspicion, post-accident, return-to-duty, follow-up), what the panel is, what consequences follow positive/refusal-to-test, what accommodations exist, and how the program complies with applicable state law (cannabis, off-duty conduct, lawful-product statutes). DOT-regulated employers also need the supplemental DOT policy elements required by Part 40.
2. Panel choice
- DOT-regulated: Use the DOT 5-panel.
- Most non-DOT employers: The standard 5-panel is the default.
- Healthcare and safety-sensitive non-DOT: Consider the 10-panel to include prescription depressants.
- Cannabis-restricted jurisdictions: Consider the 4-panel dropping THC for non-safety-sensitive roles. See cannabis & state law.
3. Specimen
Urine remains the default and is the only currently operational specimen under DOT regulation (oral fluid authorized in 2023 but pending HHS lab certification). Some employers use saliva for reasonable-suspicion and post-accident testing where observed collection is valuable. Hair is occasionally used for pre-employment in non-DOT contexts that prioritize long lookback, but it is not federally approved and has documented bias concerns.
4. Collection site / vendor
Choose a national or regional collection network with trained collectors, eCCF (electronic Custody and Control Form) support, observed-collection capability where required, and post-accident on-site dispatch. For DOT-regulated programs, collectors must be trained to the DOT collector qualification training requirements (Part 40, Subpart C).

DOT-regulated specimens must be tested by a SAMHSA-certified laboratory. Non-DOT employers should still use a SAMHSA-certified lab — there is no real reason not to, and it strengthens the defensibility of the program. The lab handles screening, confirmation testing by GC-MS or LC-MS/MS, and result reporting to the MRO.
Laboratories (example listings)
Example National Lab
SAMHSA-certified laboratory with nationwide collection-site coverage.

For DOT-regulated tests, an MRO is required. Even where not required, MRO review is the difference between a test program that produces defensible verified results and one that doesn't. Choose an AAMRO-certified or MROCC-certified physician with experience in your industry. See MRO & confirmation for the process detail.
MRO services (example listings)
Example MRO Service
AAMRO-certified physicians handle verification and donor interviews for regulated and non-regulated programs.

DOT-regulated programs require at least one hour of training on alcohol misuse and one hour on drug use indicators for supervisors who may make reasonable-suspicion determinations (FMCSA Part 382.603). Non-DOT employers should at minimum train supervisors to recognize signs of impairment and to follow the documented referral process for testing decisions.
Designated Employer Representatives (DERs) for DOT-regulated programs need their own training on the receipt and handling of test results, removal-from-duty procedures, and the return-to-duty process.
8. Records and program management
DOT-regulated employers must maintain testing records for specified periods (most records 1–5 years; some documents indefinitely). Maintain a chain of custody for every specimen, a documented random testing program with auditable selection records, and a documented response to any positive/refusal/SAP referral.
