QED Saliva Alcohol Screening Test
The QED saliva alcohol screening test is one of the first devices to be approved by the U.S. Department of Transportation (DOT) as an Alcohol Screening Device. DOT approval means that the Q.E.D. reliably and accurately detects alcohol at the 0.02 concentration or higher, and does not give false positive readings when no alcohol is present. DOT approval allows users to use the Q.E.D. for alcohol screening tests required by Dept. of Transportation regulations.
QED Gives Semi-Quantitative Results
Because the proportion of alcohol in saliva is directly related to the proportion of alcohol in blood, the QED device can accurately measure intoxication levels. Alcohol in the saliva creates a column of vivid reddish-purple color. The user reads the device at the upper limit of the color using the scale, exactly like reading a thermometer. If no alcohol is present no color develops.
As Accurate as Blood Alcohol Test
The QED device virtually duplicates blood alcohol results. Studies have demonstrated a .98 correlation (1.00 is a perfect correlation) between saliva test results with the QED and laboratory blood alcohol results.
