Alco-Screen is a rapid, highly sensitive method to detect the presence
of alcohol in saliva and provide an approximation of relative blood
alcohol concentration. Since it is well established that the
concentration of alcohol in saliva is very close to that in the blood,
saliva is the preferred specimen for alcohol testing. The product in the green box detects blood alcohol levels from 0.02% to 0.30%
BAC. The Alco-Screen 02 product detect blood alcohol at 0.02% and
above. Alco-Screen 02 is D.O.T. Approved and is the most affordable yet
accurate rapid test on the market.
