How should I exhale in Acetrack to get successful measurements?
Exhale as steadily as possible with even pressure for approximately five seconds. The pressure level is visually shown in the app while exhaling.
What does the ppm value mean?
The measured value is the fraction in ppm (parts per million) of acetone in your exhalation. This is an individual value corresponding to your level of ketosis. High levels of acetone mean that you are in ketosis and low levels mean that you are not.
Is the measured value affected by what you had in your mouth recently?
Yes, the device reacts to lingering mouth gases. This means that if you consume anything and then immediately perform a test, you will receive higher measured values.
When is it best to measure ketosis?
Ideal for measuring ketones are in the morning before you have put anything in your mouth, directly after exercise or a couple of hours after any meal or snack.
