QED A150 DOT Approved Saliva Alcohol Test Kit


Please note: QED Saliva Alcohol Test comes in cases of 10.

The Q.E.D. Saliva Alcohol Test is the only DOT Approved and CLIA Waived alcohol saliva test. This test is an on-site, low-cost alternative to breath or blood alcohol testing and provides instant results on the spot. The test is easy to operate and provides quantitative results as accurate as a blood test. The test is designed to be administered by professional users. The Q.E.D. test is to be administered by a certified Screening Test Technician or trained professional.

This test is performed using saliva by swabbing the mouth and then pressing the saturated swab into the red test center. It will run like a thermometer, with both a control line and a line indicating the level of alcohol in the system of the individual detecting the blood alcohol level of an individual up to 0.15 BAC.

If you're an organization in need of an instant saliva blood alcohol test, then they QED test may be perfect for you.

What does a positive reading look like with the Q.E.D. test?

When a Q.E.D. 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. Positive test results develop in approximately 2 minutes.

How hard should I press down with the Q.E.D. 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 Q.E.D.® 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 Q.E.D. test measure residual alcohol in the mouth or is it measuring the alcohol within the entire body (blood stream)?

Alcohol from alcoholic beverages (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 Q.E.D. 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.

Will the Q.E.D. test react with ketone often found in the saliva of diabetic patients?

No. Unlike breath analyzers and other saliva tests, the Q.E.D.® test is specific to ethyl alcohol and will not cross-react with acetone and ketone produced by diabetic patients.

Will the Q.E.D. device work if it is stored at temperatures outside the range on the packaging?

Storing and using Q.E.D. tests at room temperature (15-30ºC, 59-86ºF) ensures optimal performance and a full shelf life. However, the Q.E.D.® test will work fine if exposed to temperatures outside that range for limited periods. The Q.E.D. device was tested under a wide range of temperatures and storage conditions -- simulating the inside of a vehicle glove box on a hot summer day (about 120ºF) and the lonely cold of North Dakota in January (about 0ºF). In all cases, the test performed as it should. Before using a Q.E.D. Saliva Alcohol Test exposed to extreme heat, allow the device to cool to room temperature; if the Q.E.D. device is exposed to extreme cold, put it into a pocket to warm it up.

How can companies using the Q.E.D. test in very remote areas comply with the DOT's requirement that confirmation tests on positive screening tests must be conducted within 30 minutes?

The DOT will accept results of confirmation tests conducted more than 30 minutes after a positive screening test. Look to 49 CFR Part 40 section 40.65, paragraph (b). The DOT added a sentence which directs the Breath Alcohol Technician (BAT) to simply explain "why?" if a confirmation test is done more than 30 minutes after a screening test. This is not a fatal flaw.

Why should I buy the Q.E.D. Saliva Alcohol Test if I need an Evidential Breath Testing (EBT) to confirm positive test results?

The Q.E.D.® test is much less expensive to operate than a breath test, unless you conduct a very high volume of tests in a central location. By and large, each test done on saliva instead of breath saves money. Plus, performing two independent tests is more legally defensible on the rare occasion an employee does test positive for alcohol.

Instructions for Use:

Instruct the donor not to place anything in their mouth including food, gum, drinks and tobacco for 10 minutes prior to saliva sample collection.

1: Instruct the donor to swab the inside of their mouth including cheeks, gums and under the tongue for 30-60 seconds until the cotton swab is thoroughly saturated.

2: Place the QED test device on a flat surface. Gently insert the collection swab into the entry port of the testing device. Apply gentle yet steady pressure and hold until the pink fluid reaches the QA Spot at the end of the device.

3: After two minutes, read the alcohol concentration at the highest point of the purple bar. This will indicate the donor's current blood alcohol level. Please note: Results read after 2 minutes should be considered an invalid test result.

Works well

Works well. Ive used a few different kinds of these tests in the field over the years and this one is by far the most reliable one. I would recommend it to any company that needs to test for alcohol consumption on the spot.

Instructions are easy to follow. the only thing theyre missing is tellingyou how to deal with a drunk who is being a pain in the asss when your tryine to test them


I prefer doing breathalyzer tsts because they are so much faster and easier to get a sample

I prefer doing breathalyzer tsts because they are so much faster and easier to get a sample. This test requires a lot of waiting, which I didnt like. Id say save everyone a headache and go with a breathalyzer test.

It's significantly cheaper than a breath test or a blood test

It's significantly cheaper than a breath test or a blood test, although it is as accurate. There really is no need to spend a lot for alcohol tests. We've been using this test for a while, and it's been completely reliable.
