Oryza sativa Ab.IgE/IgE.total
Measures rice-specific IgE antibodies expressed as a percentage of total IgE.
Why This Biomarker Matters
Confirms rice allergy and helps determine clinical significance by comparing to total allergic burden. Guides dietary management, particularly important in Asian and other rice-based cuisines.
Overview
This test measures rice-specific IgE antibodies as a percentage of total IgE in blood. Rice allergy is uncommon in developed countries but more prevalent in rice-consuming populations. It can manifest as oral allergy syndrome, gastrointestinal symptoms, or atopic dermatitis flares. Reporting as a percentage of total IgE helps contextualize the significance of the allergen-specific response. A positive result indicates sensitization to rice proteins. This test is particularly useful for individuals in rice-dependent diets experiencing unexplained allergic symptoms.
