What role does IgE Allergietest play in menopause?

The role of IgE allergy testing in menopause is not well-defined by current evidence. IgE tests measure specific immunoglobulin E to diagnose immediate-type allergies. During menopause, declining estrogen levels may theoretically influence immune responses and histamine release, potentially altering allergy symptoms. Some observational studies suggest increased allergy prevalence or symptom severity in perimenopause, but direct evidence linking IgE levels to menopausal symptoms is limited and inconsistent. The evidence is mostly mechanistic or based on small studies. IgE testing can be useful if new or worsening allergy symptoms occur during menopause, but it is not recommended as a routine screening tool for menopausal complaints. Importantly, normal IgE does not rule out hormone-related symptoms like hot flashes or mood changes. Clinical context and symptom history are essential. Evidence: unclear.
