Breath testing: Tips & Technique

Tips for Successful Breath Testing

If you’re new to breath testing, here are some tips to help ensure you’re using your device correctly and getting the most accurate results.

Before You Start

• Take your breath tests in a relaxed state — avoid testing immediately after exercise or rushing upstairs.
• Try to test indoors where conditions are stable. Extreme environments (very cold, hot or humid) can affect your device’s performance.
• Make sure your lips and mouth are clean and dry before testing - you want to avoid food particles or liquid getting into the mouthpiece.
• Sit upright - avoid testing while reclined or lying down.

During the 3-second Countdown

• Don't hold your device too close to your nose or mouth as the sensors may pick up even a faint exhale.
• Keep your device a small distance from your face and bring it to your mouth slowly once ready to test.

During the Test

• Hold your device upright and straight, so your breath travels smoothly through it rather than against the inner surface.
• Do not blow forcefully into the device. A gentle, steady exhale gives the most accurate result.
• When prompted, exhale gently and consistently for 5 seconds. A good trick: imagine you’re cooling soup on a spoon — you wouldn’t blow hard, just a soft, steady breath.
