Alco-Screen II Alcohol Test Procedure 
Abstain from placing anything in the subject’s mouth for fifteen (15) minutes prior to beginning the test. This includes non-alcoholic drinks, tobacco products, coffee, breath mints, food, etc. 
Open the foil package and remove the test strip. The preservative packet is not needed to perform the test and should be discarded. Observe the reactive pad on the end of the test strip. The pad should be a light cream color. A test strip with a reagent pad which has a colored line or is otherwise discolored must be discarded. 
Saturate the reactive pad with saliva from a sputum cup or by applying saliva directly to the pad. Immediately start timer. After ten seconds, shake off excess saliva. 
At four (4) minutes, observe the results on the reactive pad. Reading the results may be made easier by placing the test on a white background. The development of a distinct colored line across the reactive pad indicates the presence of alcohol greater than 0.02% (0,2‰) BAC. Results obtained after more than five (5) minutes may be erroneous. Positive Result: Blood alcohol above 0.02% 
Negative: Blood alcohol less than 0.02%. 
"Legal limit varies according to testing location".
