The Alco-Level saliva alcohol test uses an enzyme reaction to detect the presence of alcohol in saliva. Scientists have established that the concentration of alcohol in saliva is very closely correlated to the concentration of alcohol in blood. Therefore, a saliva alcohol test is a convenient and quick method to detect the presence of alcohol in blood and to estimate intoxication levels.
The Alco-Level can be used as a qualitative pass/fail test as well as a semi-quantitative test to estimate alcohol intoxication levels. The Alco-Level detects alcohol levels from between 0.02% and 0.10%. The ability to detect intoxication levels at 0.02% makes the device ideal for applications where very low levels of intoxication are prohibited.
The Alco-Level device consists of a thin strip with a collector sponge on one end and a reagent treated pad in the middle. The user collects a saliva sample using the collector sponge on the end of the strip, and then bends the strip to transfer the saliva to the yellow reagent pad. Any alcohol in the saliva creates an enzymatic reaction that immediately turns the yellow reagent pad to shades of green.
Any green color within 30 seconds of applying the saliva to the reagent pad indicates the presence of alcohol. The user estimates alcohol intoxication levels by comparing the color change against four (4) color standards printed on the test representing 0.02%, 0.05%, 0.08%, and 0.10% intoxication levels.
