Allergens, Food, Seafood Profile
Also known as: SEAFOOD
Use
The Allergens, Food, Seafood Profile is used to quantitatively assess the presence of allergen-specific IgE antibodies to common seafood allergens including Codfish/Whitefish, Crab, Lobster, Shrimp, and Tuna. This test helps in the diagnosis of seafood allergies, facilitating the correlation of laboratory results with clinical history and in vivo reactivity. It provides a comprehensive profile for patients suspected of having allergic reactions to seafood and can help guide dietary adjustments and management strategies for those with confirmed allergies.
Special Instructions
Not provided.
Limitations
The concentrations of allergen-specific IgE detected by this test may not directly correlate with the severity of clinical allergic reactions or skin test results. A negative result does not rule out a clinical allergy or potential for anaphylaxis. Results that fall in the range of 0.10-0.34 kU/L should be interpreted with caution and are recommended for specialist use, as the clinical relevance is undetermined. Therefore, it's essential to interpret laboratory results in conjunction with clinical history and any known in vivo responses to specific allergens.
