Is AllergieCheck | IgE-Antikörper Test useful for fertility?

The AllergieCheck (IgE antibody test) is not useful for fertility assessment. IgE tests detect sensitization to specific allergens, not clinical allergy or fertility issues. Professional guidelines (EAACI, AAAAI, DGAKI) explicitly reject unspecific IgG/IgG4 food tests; for IgE, sensitization does not equal allergy. There is no scientific evidence linking IgE levels to fertility. While hormonal, metabolic, or inflammatory markers (e.g., CRP, IL-6, TNF) can influence fertility, a simple IgE check provides no relevant information. Using this test for fertility could lead to misinterpretation and unnecessary costs. For fertility evaluation, specific hormone panels and clinical workup are recommended.
