What does the Codfish Specific IgE test measure?

Q: What is Codfish Specific IgE?

The dominant fish allergen is the muscle calcium-binding protein parvalbumin (Gad c 1 in cod), which is heat- and digestion-stable and highly cross-reactive across bony fish species. Cooking rarely abolishes reactivity, and parvalbumin content varies between species, which underlies the variable cross-species tolerance some patients report.

Q: Why is Codfish Specific IgE measured?

Cod sIgE serves as a marker of bony-fish sensitisation; a positive result frequently predicts reactivity to multiple fish because of parvalbumin homology. It does not predict shellfish reactivity, which is a biologically unrelated tropomyosin-driven sensitisation, so the two must be assessed separately.

Codfish Specific IgE (f3 Cod sIgE) is a clinical biomarker used in food-sensitivity-allergy assessment. The dominant fish allergen is the muscle calcium-binding protein parvalbumin (Gad c 1 in cod), which is heat- and digestion-stable and highly cross-reactive across bony fish species. It is measured in 1 laboratory test on BiomarkersLabs.com.
