The Q.E.D. Saliva Alcohol Test is the most accurate disposable alcohol test. Others disposable tests just detect the presence of alcohol at a certain level or give an approximation of the alcohol level. The QED gives quantitative results that have a .98 correlation with the actual blood alcohol tests.
The Q.E.D. offers an alternative to paying high prices for electronic alcohol detection devices and calibration equipment. This device is perfect for an application of just a few people or many people, since the test can be purchased individually.
