Wheat IgG4
Clinical Use
Order TestUse
This test measures IgG4 class antibodies specific to wheat (Triticum aestivum). It can be used to assess immune-mediated responses to wheat in the context of food-related symptoms or disorders, contributing to clinical evaluation of possible wheat sensitivity or intolerance. Interpretation should be integrated with clinical history and other diagnostic findings.
Special Instructions
Not provided.
Limitations
IgG4 antibody levels may reflect exposure and tolerance, not necessarily allergy or pathogenic immune response. Elevated levels are not diagnostic of true food allergy, and context—and potentially further testing—is required for clinical interpretation.
