QED Test Frequently Asked Questions
What does a positive reading look like with the QED® test?
When a QED® test result is positive, a dark purple color bar forms within the measurement scale. This color is distinctly darker than the pink or orange color seen as the sample fills the device. The color bar on a positive test -- the same color seen in the QA Spot™ -- develops in 2 minutes.
How hard should I press down with the QED applicator?
Gently apply slow and even pressure when placing the swab in the entry port. Too much pressure can jam the test. For best results, gently twist the collector into the entry port until the cotton touches the red filter pad and then begin pressing.
What does the Clinical Laboratory Improvement Act (CLIA) waiver mean for work site testing?
Because work site testing is considered forensic testing, CLIA regulations do not apply. The waived status for the QED Saliva Alcohol Test under CLIA ’88 makes testing easier in hospitals, rehabilitation centers and treatment facilities where our test is used as an in-vitro diagnostic tool.
Does the QED® test measure residual alcohol in the mouth or is it measuring the alcohol within the entire body (blood stream)?
Beverage alcohol (ethyl alcohol) is absorbed directly and unchanged into a person’s body and is evenly distributed throughout the blood stream and other bodily fluids, including saliva. The QED test measures the amount of alcohol in bodily fluids, commonly called blood-alcohol concentration, or BAC. Residual alcohol in the mouth just after a person takes a drink is quickly absorbed, swallowed, or evaporated, and a person’s mouth is "clear" of residuals 10 minutes after eating or drinking.
One customer asked if "using the QED Saliva Alcohol Test was just a matter of spitting on to those little thermometers?"
The QED test does provide laboratory accuracy with on-site simplicity, but spitting is not polite and we wouldn’t want to support bad manners.
When are you going to make a Screening Test Technician (STT) training video for non-Department of Transportation (DOT) settings?
While the STT Training Video is DOT-approved and covers the DOT regulations, it should not be viewed as a "DOT only" product. Companies with alcohol testing policies would do well to use the DOT program as a model, in case their program was ever challenged. Similarly, test technicians should consider DOT-certification as a way to further validate their ability to do the testing.
How can a company use your Screening Test Technician (STT) training video to certify an STT if no one at the company is already certified?
The DOT requires that the STT Training Video Facilitator be someone with at least one year’s experience working as an STT or training STTs. Without that experience, a Facilitator must complete a "train the trainer" STT course offered by OraSure Technologies or an authorized QED Distributor or STT Trainer.
8. Can a "facilitator" become certified while taking a student through the video course?
No. The DOT ruled that STTs cannot certify themselves. However, once a student is certified, the student can be the facilitator, and the facilitator becomes the student.
