Alco-Screen Alcohol Test Procedure 
Abstain from placing anything in the 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. Observe the reactive pad on the end of the test strip. The pad should be a light cream color. A test strip with a regent pad which is dark tan color or otherwise discolored must be discarded. 
Saturate the reactive pad end of stick with saliva from mouth or sputum cup. Immediately start timer. Remove test pad/stick from mouth and wait two minutes. 
At two minutes observe the color changes (if any) in the reactive pad. A color change of green or blue indicates the presence of alcohol and a positive result. Results obtained after more than 2 minutes and 30 seconds my be erroneous. Compare test pad with the color chart printed on the back panel of foil package. Within 15 seconds choose the closest color match to estimate the alcohol concentration. Interpretation: Negative - No color change on reactive pad .Positive - Reactive pad changes color in 2 minutes
