This simple blood alcohol test provides quick, accurate results! All you have to do is squeeze the center of the tube to activate the test and then blow through the center. Based on your Blood Alcohol Content (BAC), the crystals will either stay yellow indicating a negative result, or change to blue/green, indicating a positive result.
It’s disposable and designed for one time use, with a compact size that makes it easy to fit into any pocket or purse. There’s a .02% threshold BAC tester available, perfect for zero tolerance environments, whereas the .05% and .08% tests are more commonly used for the prevention of alcohol related accidents. Simply choose the test that fits your needs. Buy it here for $6.49.
