Self-Test for Breath Alcohol

Alcohol, Breath Test

What Affects the Test

No home test is 100% accurate. The results may not be helpful if you:

  • Have trace amounts of alcohol left in your mouth from an alcoholic drink or even a mouthwash.
  • Smoke. Do not smoke for 1 to 5 minutes before doing the test.
  • Have had a drink within 30 minutes of performing the test. Your actual blood alcohol level may continue to rise after the test.
