Teen’s Anaphylaxis from Energy Drink Highlights Gap in Fish Collagen Allergy Testing

The case, presented at the ACAAI 2026 meeting, reveals that common allergy tests miss collagen proteins, which are increasingly used in supplements. Experts warn consumers with fish sensitivities to scrutinize labels for hidden marine ingredients, as processing does not always eliminate allergenic risks.
