How to prepare for IgG Unverträglichkeit Frauen

Preparing for an IgG test for suspected food intolerance (often marketed as 'IgG food intolerance test') requires a critical perspective: the scientific evidence for IgG-based testing is weak. Major allergy organizations (e.g., EAACI, AAAAI) advise against using IgG tests to diagnose food intolerance, as IgG antibodies commonly reflect normal immune exposure to foods and do not reliably correlate with symptoms. If you still choose to take such a test, be aware that results often yield false positives and may lead to unnecessary dietary restrictions. To prepare: keep a detailed symptom and food diary for at least two weeks, recording all meals, drinks, portion sizes, and any symptoms (bloating, diarrhea, skin issues, fatigue). Do not avoid any foods before the test, as this would distort the baseline. Consult a doctor or registered dietitian beforehand to rule out other causes such as lactose intolerance, fructose malabsorption, celiac disease, or irritable bowel syndrome. For women, hormonal fluctuations (menstrual cycle, pregnancy, menopause) can influence gastrointestinal symptoms – note these in your diary. After the test, do not interpret results alone; discuss them with a healthcare professional. A positive IgG result alone does not justify a long-term elimination diet. A more evidence-based approach is a controlled elimination and rechallenge diet under medical supervision. The overall evidence level is 'mixed' to 'unclear', as no robust clinical trials support the clinical utility of IgG testing for food intolerance.
