Allergens, Food, Shell Fish Profile
Also known as: SHELLFISH
Use
The Allergens, Food, Shell Fish Profile test is used to quantify specific IgE antibodies to shellfish allergens in patient serum, helping to evaluate if a patient has an allergy to certain types of shellfish. This kind of testing is crucial for diagnosing potential food allergies and assessing the risk of allergic reactions, which could range from mild symptoms to severe anaphylactic responses. The test results help healthcare providers make informed decisions about dietary recommendations and necessary precautions to prevent allergic reactions.
Special Instructions
Not provided.
Limitations
Allergen specific IgE concentrations measured in this test may not directly correlate with the severity of allergic reactions when patients are exposed to the allergens through ingestion. The clinical relevance of allergen IgE levels between 0.10-0.34 kU/L is undetermined, which underscores the need for clinical correlation by an experienced allergist. A negative result does not eliminate the possibility of a shellfish allergy or reaction.
