Accurate and Blood-equivalent

In clinical trials, saliva alcohol levels measured with Q.E.D. demonstrated high correlation to blood analysed by gas chromatography (r = 0.98) and produced no false positive or false negative results.
Workplace Testing 

Q.E.D. can be used as an accurate screen in place of blood tests and is approved by the US Department of Transportation (DOT) and Food and Drug Administration (FDA) for mandatory workplace programs.
