How Does an Oral Fluid Drug Test Work?
Instead of providing a urine specimen, the donor provides a small oral fluid (saliva) sample using a specially designed collection device.
The collection is completed under direct observation without compromising privacy, making it one of the most secure specimen collection methods available.
To ensure accurate results, donors should avoid eating, drinking, smoking, chewing gum, or using mouthwash for at least 10 minutes before specimen collection.
Once collected, the specimen is screened immediately.
Negative Results: Reported the same day.
Non-Negative Results: Sent to a certified laboratory for confirmatory testing. Confirmation results are generally available within 5–8 business days, although turnaround times may vary depending on the specific testing requirements.
