The tolerance test used in the CarboCeption App has a strong scientific basis: a questionnaire which was developed by university based physician scientists for the measurement of symptoms which can occur after ingestion of carbohydrates (adult carbohydrate perception questionnaire, aCPQ).

Symptoms are measured on a scale, the ends of which represent extreme conditions of a symptom.

• Symptoms are measured repeatedly before and after taking a test substance or a test food.
• The severity of the symptom is marked.

Prepare your test substance and measure the amount you want to test with a cup or table spoon or select according to serving size.

The CarboCeption App will lead you through the following steps:

1. You measure your baseline symptoms that are present before drinking the test solution on the visual scale:
   • between the descriptions "none" and "very severe" you can measure the presence and severity of symptoms.
   • you will be asked for symptoms which are typical for carbohydrate intolerance.
2. You ingest the test substance, test food or solution which you have prepared.
3. Every 30 minutes your alarm will remind you of the next symptom measurement.
4. Test duration is 3 hours
5. After the test you will be informed about results and recommendations.
