high blood alcohol level has been reached and in such cases, further test should be
carried out later in the day.
3. During testing, any alcohol traces left in your mouth will increase the value of the
blood alcohol concentration level. Remove these traces before testing. Highest
accuracy is achieved 30 minutes after drinking.
