Oral Fluid Drug Testing
Saliva/ oral fluid-based drug tests can generally detect use during the previous few days are becoming more prevalent and harder to adulterate than the urine drug tests since the sample can be obtained under direct supervision. Results can be read in minutes.
Detection in saliva tests begins immediately upon use.
Oral fluid specimen collection is simple and non-invasive. Collection can occur at any time or location without embarrassment to the donor.
The specimen can be collected from the donor under direct observation, thus minimizing the potential for specimen tampering and/or adulteration. Oral fluid drug concentrations can be related to plasma free-drug concentrations and the pharmacological effects of drugs. As a result, oral fluid drug concentrations can provide information similar to that provided by plasma or blood drug concentrations.
