The Q.E.D. Saliva Alcohol test is a quantitative test used for the quick determination of alcohol in saliva.
Ethanol is the most common toxic substance encountered in medical cases. Not only is it lethal in its own right, but is commonly a contributing factor in many accidents.
The distribution of alcohol in saliva and blood is well established with the concentration of ethanol in saliva being approximately 1.07 times higher than the corresponding blood alcohol level. While there is good correlation between blood and saliva alcohol levels, normal physiological variability does exist. Where exact blood alcohol concentrations must be known, blood samples should be taken from patients who give positive Q.E.D. alcohol test readings.
