Allergy Specific IgG - Aspergillus Fumigatus

About This Package

**Allergy-specific IgG** is a blood test that measures the presence of immunoglobulin G (IgG) antibodies against specific allergens. Unlike IgE antibodies, which are associated with immediate allergic reactions, IgG antibodies are generally linked to delayed-type hypersensitivity responses. **Key Points:** - **Function:** IgG antibodies bind to allergens and can indicate exposure or sensitivity to specific substances. Elevated levels of IgG against certain allergens may suggest chronic or delayed allergic reactions. - **Clinical Relevance:** This test is used to identify potential food intolerances or sensitivities, though its role in diagnosing classic allergies is limited. It may provide insights into underlying sensitivities or chronic conditions. - **Diagnostic Use:** It helps in understanding immune responses to specific allergens, guiding dietary or lifestyle adjustments. However, it is less commonly used than IgE testing for diagnosing immediate allergic reactions. The allergy-specific IgG test is part of a broader approach to allergy testing, focusing on identifying potential delayed hypersensitivity reactions.
