Be it pregnancy tests or measuring devices for determining blood sugar - self-tests for at home have long proven themselves in many areas and can support and supplement the cooperation with the doctor. However, tests for food intolerance for home use are quite new. The offer includes hydrogen breath tests for diagnosing lactose, fructose and sorbitol intolerance or gluten tests that check for celiac disease. The big advantage is the time saved compared to a visit to the doctor with long waiting times.
Those affected should note, however, that multiple intolerances can play a role in digestive problems. Therefore, various tests are often necessary to find out which ingredients cause the symptoms. In addition, the information given on the instructions for use is not always sufficient and is also not always correct. Even small deviations in the implementation can falsify the result. In addition, the tests do not include eating habits. These can influence the intestinal flora and thus the measurement result. Problems with the return of the samples cannot be ruled out and can have an impact on the result. The person concerned must bear the costs for self-tests. If a doctor conducts the tests, the health insurance company pays the costs.
Even with a correct evaluation, the individual circumstances of the patient are not taken into account. A personal final discussion, advice on further diagnostic measures and an individual nutritional plan are missing. "In the event of a positive test result, it is important to find out from reputable sources about the diet resulting from the diagnosis in order to be able to live again free of symptoms," explains nutrition and health educator Doris Paas.
