Oral Fluid testing:

From Quest Diagnostics

The use of oral fluid (saliva) as a biological specimen for the detection of drugs of abuse is growing in popularity within the workplace. The increased popularity of oral fluid drug testing is due to inherent advantages over the standard urine drug test. Oral fluid specimen collection using Intercept 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.

Consideration should be given to the effect that some drugs or medical conditions have on the donor’s ability to secrete oral fluid. As a result, oral fluid may not be available from all individuals at all times.2 Intercept tests for the following drug classes:

Orals fluid specimen six-panel test:

Analyte Screen Cutoff Confirmation Cutoff
Amphetamines 100 ng/mL 40 ng/mL
Methamphetamines 40 ng/mL 40 ng/mL
Opiates 10 ng/mL 10 ng/mL
Benzoylecgonine 5 ng/mL 2 ng/mL
Phencyclidine 1 ng/mL 0.5 ng/mL
Marijuana metabolite 1 ng/mL 0.5 ng/mL

The table below shows the detection window for drugs of abuse using oral fluid.

Drug Detection Window for Oral Fluid
Amphetamines 24-36 hours
Cocaine/Metabolite 24-36 hours
Opiates 24-36 hours
PCP 24-36 hours
THC/Metabolite Less than 24 hours
