Do you suspect that you have a fish allergy even when the testing was negative? A study in the Journal of Allergy and Clinical Immunology: In Practice explains that fish collagen may be responsible for this problem. The collagen in fish does not dissolve in solutions used for commercial diagnostic tests. There may not be enough fish collagen allergen in these testing extracts to get a positive result. Therefore, fish allergy may be underdiagnosed.
This study from the Medical University of Vienna examined 101 patients with fish allergy. Roughly 20% of these patients had tested positive for the collagen fish allergen. Some of these patients only tested positive for collagen and not for the most common fish allergen called parvalbumin.
Food allergy rates are increasing worldwide. Fish allergy is one of the most common food allergies in the United States, yet it is underdiagnosed. This food allergy has one of the highest chances of developing anaphylaxis, which is a life-threatening allergic reaction. However, we are learning more about how to diagnose and treat fish allergy. Even our very own Dr. Zachary E. Rubin recently published a study on the treatment of seafood allergy.
