Non-DOT workplace testing
Your policy sets the rules. State law sets the floor.
Outside federally regulated work, nobody hands you a panel or a procedure. You choose them, in a written policy. What you do not get to choose is the procedural standard, because North Carolina sets that for every private employer testing current or prospective employees.
Panels
Five, ten or twelve, and why it matters.
A panel is simply how many substance groups the laboratory looks for. Larger is not automatically better. A panel that flags substances your policy has no stated position on creates a decision you have not prepared for.
5 panel covers the classic core: marijuana, cocaine, opiates, amphetamines and PCP. It is the cheapest and the least informative.
10 panel adds groups such as barbiturates, benzodiazepines, methadone, propoxyphene and methaqualone. This is the common choice for safety sensitive non-DOT roles.
12 panel extends further into prescription opioids and synthetic substances. Worth considering where the workforce has known exposure risk, and worth pairing with a Medical Review Officer so legitimate prescriptions are handled correctly rather than becoming employment decisions.
Whichever you choose, write it into the policy by name. A policy that says only "a drug test" is very hard to enforce consistently.
North Carolina requirements
Five things state law requires of you.
The Controlled Substance Examination Regulation Act, G.S. 95-230 through 95-235, applies to private employers and to state, county and municipal employers testing employees or applicants. DOT required testing is exempt.
- Use an approved laboratory. One that has demonstrated satisfactory performance in the HHS forensic urine drug testing program or the College of American Pathologists programme for the tests being run.
- Confirm positives by mass spectrometry. Gas chromatography with mass spectrometry, or an equivalent scientifically accepted method. For current employees, every positive screen must be confirmed.
- Collect under sanitary conditions and preserve dignity. The statute says so explicitly, and says samples may be collected on site.
- Retain positive samples for at least 90 days from the date the confirmed positive result is delivered to the employer.
- Allow the employee to retest. A confirmed positive sample must be made available for retesting at an approved laboratory of the employee's choosing, at the employee's expense.
Penalty
Violations carry a civil penalty of up to $250 per affected examinee, capped at $1,000 per investigation by the Commissioner of Labor, with a two year limitation period running from the violation.
One useful distinction
Applicants and current employees are not treated the same.
North Carolina draws a line between the two, and it changes what you are allowed to do at the screening stage.
| Prospective employee | Current employee | |
|---|---|---|
| Screening method | Single use test device permitted | Approved laboratory only |
| Confirmation of a positive | Required, unless the examinee signs a written waiver | Always required |
| Retest right | Yes | Yes |
