Quick Answer
Instant drug testing gives a preliminary result at the time of collection. Employers use it for non-DOT testing under their own policy. A non-negative instant result is not a final result and should be confirmed by a laboratory before any decision. DOT-required tests cannot use instant tests.
When Employers Use Instant Testing
- Pre-employment testing for non-DOT roles with a fast start date.
- High-volume hiring, such as staffing, warehouse and hospitality placements, where a quick negative helps keep start dates.
- Employers whose policy accepts instant negatives and sends non-negatives to a lab.
Instant vs. Lab-Based Testing
Lab-based testing sends the specimen to a certified laboratory, which can confirm results and is required for DOT testing. Instant testing gives a preliminary answer at collection. Many employers use instant tests for speed and lab-based testing for confirmation, regulated roles and situations where a defensible result matters most.
Before You Use Instant Tests
Some states restrict or regulate on-site or instant workplace testing, and some require lab confirmation of a non-negative result. Review your policy with counsel for the states where you test. For DOT-covered employees, use DOT drug testing.
