AlcoScreen Alcohol Saliva Test Kit

Alco Screen DIRECTIONS NOTE: Do not place 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.

1. 1. 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. 2. Insert test pad into mouth and saturate with saliva. Remove test pad and wait two minutes. 3. At exactly two (2) minutes observe the color change (if any) in the pad. A color change of green or blue indicates the presence of alcohol and a positive result. Results obtained after more than 2.5 minutes may be erroneous and should not be used.Estimate the approximate blood alcohol concentration by comparing the color of the pad to the color chart on the back panel of foil package. INTERPRETATION The test produces a color change in the presence of saliva alcohol ranging from a light green-gray color at 0.02% blood alcohol concentration to a dark blue-gray color near 0.30% blood alcohol concentration.

Color blocks are provided within this range to allow an approximation of blood alcohol concentration to be made. A green color that is lighter than the 0.02% color block should be interpreted as being positive to the presence of alcohol in saliva but less than 0.02% blood alcohol content. A result where the pad shows no color change (remains white or cream colored) should be interpreted as a negative result (no alcohol present). A result where the outer edges of the pad produce a slight color but the majority of the pad remains colorless should be repeated to ensure complete saturation of the pad with saliva. If the second result is the same, the results should be interpreted as being negative (no alcohol present). LIMITATIONS

• Failure to wait 15 minutes after placing food, drink, or other materials in the mouth before running the test can provide erroneous results due to possible contamination of the saliva by interfering substances.
• Waiting longer than two minutes to interpret the test can result in erroneous or false positive results.
• The test may be used to detect the presence of alcohol in fluids other than saliva. However, when used in this manner, the color chart on the package does not apply. If alcohol is present in the fluid, a color change ranging from a light green-gray to black to cocoa brown will occur as the alcohol concentration increases. Little or no color change may occur with pure alcohol (99%) due to the absence of water which is required for the color change reaction. When testing beverages, a result should not be considered positive unless the pad changes to a very dark brown or black.
• The test is highly sensitive to the presence of alcohol. Alcohol vapors in the air can sometimes be detected by the test. Alcohol is a component in many household products such as disinfectants, deodorizers, and glass cleaners. If the presence of alcohol vapors is suspected, the test should be performed in an area known to be free of these vapors (such as outside).
