Test yourself.nu Alcohol saliva test Alcohol saliva test strips can be used to quickly detect alcohol in saliva. However, they can also be used to test for alcohol in beverages.
After 2 minutes, it can be determined from saliva (up to 12 hours after use) whether alcohol has been consumed.
Compound Test strips
Usage Remove the test strip from the plastic pouch. Avoid direct contact with the reaction area at the end of the test strip. The reaction field should be cream-colored (light yellow). If the reaction field is green or dark green/gray before starting the test, the test strip should not be used.
• Moisten the reaction area thoroughly with saliva or fluid immediately through the mouth or from a cup. Immediately begin timing. • Read the result after 2 minutes. Compare the color on the reaction field of the strip with the color scale on the pouch. A color change on the strip from bright green to dark green/gray indicates the presence of alcohol. Note: After 3 minutes,
The test can no longer be read! Reading after 3 minutes can be a give a false positive result.
The following substances may affect the test result when in fluids other than saliva test. Substances that enhance color change: • Peroxide • Strong Oxidizing Agents (these agents can be found in some washing powders, bleaches and cleaning agents)
Substances that weaken the color change: 1. Ascorbic acid (Vitamin C) 2. Tannic acid 3. PyrogallolMercaptan and thiols 4. Toluene 5. Oxalic acid 6. Uric acid 7. Bilirubin 8. L-dopamine 9. L-Methydopamine 10. Methampyron
Interpretation of the test result Use only the color scale from the test strip pouch.
The color change of the reaction field on the strip will be slightly slower and less intense when testing in saliva than when testing in “aqueous” fluids.
