What to watch with IgE and allergy?

The provided context does not contain specific information about IgE or allergies. In general, IgE is an antibody involved in type I hypersensitivity reactions (allergies). Elevated total IgE can indicate allergic predisposition but is not diagnostic. Allergen-specific IgE tests (e.g., via blood or skin prick) are more informative but still require clinical correlation. DNA tests for allergy risk often have weak predictive value due to polygenic inheritance and environmental modifiers. The context here covers FADS, VDR, and MTNR1B genes, not IgE. Therefore, no evidence-based recommendations regarding IgE or allergy management can be derived from this knowledge. Consult an allergist for proper interpretation.
