Pacific Squid, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Pacific squid, identifying allergens responsible for allergic responses or anaphylactic episodes, and confirming sensitization prior to immunotherapy. It aids in investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. The presence of IgE antibodies increases the likelihood of allergic disease compared to other etiologies and defines the allergens responsible for symptoms. Testing for IgE antibodies is not useful for patients previously treated with immunotherapy to assess residual clinical sensitivity or when medical management does not rely on allergen identification.
Special Instructions
Not provided.
Limitations
The test may not be useful in patients treated with immunotherapy or in situations where allergen specificity does not influence management. Some individuals with clinically insignificant sensitivity may have measurable IgE levels. False-positive results for IgE antibodies may occur in patients with serum IgE levels >2500 kU/L due to nonspecific binding. Test results should be interpreted within the clinical context.
