Q1.Why use clear water or non-alcoholic drink before the test?
A:Residues of alcohol in mouth will affect the measured values, to get test results which reflect the human Blood Alcohol content accurately, please rinse out your mouth with water or non-alcoholic drinks to remove the residues of alcohol in mouth before using the unit.

Q2.Why do you test about 20 minutes after drinking?
A:It takes certain amount of time for the alcohol in stomach to be absorbed into blood. To get a more accurate test result which can reflect the Blood Alcohol Content well, please abstain from smoking and drinking (for at least 20 minutes) before test.

Q3.Why does the test result fluctuate between two adjacent tests when the same person is tested on the same instrument for alcohol testing?
A:After drinking alcohol, alcohol is absorbed into the bloodstream from the stomach. As time goes by, the alcohol in the blood will be absorbed and digested. Alcohol is metabolized in the liver. Adult healthy liver can decompose about 10mL-20mL per hour of alcohol, so the blood alcohol content (BAC) may fluctuate within a few minutes.

Q4.Two people drink the same amount of alcohol, why is the result of the alcohol test different?
A:Tolerance to alcohol varies from one person to another, and can be affected by such factors as genetics, constitution, gender, percentage of body fat, adaptation to chronic alcohol use, and synergistic effects of drugs. same amount of alcohol, different person the Blood Alcohol Content maybe different, so the test result maybe different.
