Risks and limits of IgE Allergie Frauen

Allergy tests for women (e.g., specific IgE) indicate sensitization, not necessarily clinical allergy. Many women with elevated IgE have no symptoms, while others with negative tests may still have allergies. Prevalence differs by sex – women more often suffer from delayed-type allergies (e.g., contact dermatitis) and autoimmune conditions that are not captured by IgE tests. Hormonal cycles, pregnancy, and menopause modulate immune responses, potentially skewing results. Consumer DNA tests like those from MyBody-X offer only risk hints based on SNP associations with small effect sizes; they are not diagnostic. Evidence for sex-specific predictive power of IgE tests is moderate. Key limits: lack of standardization between labs, high false-positive rates, and neglect of lifestyle/environmental factors. Women should understand that such tests are only one piece of the puzzle and cannot replace clinical evaluation with history and provocation tests. They are not suitable for self-diagnosis or treatment decisions.
