text: Alcohol test strips use saliva to test for alcohol consumption. AlcoScreen alcohol test strips are available in two variations. The alcohol test strips, AlcoScreen 02, are DOT approved and provide a pass/fail result for alcohol consumption above 0.02%. AlcoScreen Regular provides a quantitative reading approximating the blood alcohol concentration (BAC) from 0.02% to 0.30%. These alcohol test strips may be also used to detect the presence of alcohol in liquids such as drinks. As an alternative to alcohol test strips, we offer the DOT approved QED A150 saliva test, the budget-friendly BreathScan items and the AlcoMate Premium breathalyzer.
