Allergen, Food, Walleye Pike IgE
Also known as: PIKE
Use
The Allergen, Food, Walleye Pike IgE test is used to detect specific IgE antibodies to the Walleye Pike allergen in serum. This test aids in diagnosing allergic conditions related to the Walleye Pike, by quantifying the level of IgE to this specific allergen, which may correlate with the likelihood of an allergic reaction. However, the concentration measured does not necessarily predict the severity of an allergic reaction upon exposure to the allergen. Results must be correlated with clinical history and in vivo reactivity to specific allergens.
Special Instructions
Patients should avoid multiple encounters before the test to ensure consistent IgE levels. Serum should be separated from cells as soon as possible or within two hours of collection to maintain optimal sample quality. For situations involving multiple allergens, consult 'Allergen Specimen Collection Instructions' for detailed guidelines.
Limitations
The concentration of allergen-specific IgE measured may not correlate with the severity of the clinical response upon exposure to the allergen or skin testing results. A negative result cannot rule out the possibility of an allergy or even anaphylaxis to the Walleye Pike allergen. Results should be used in conjunction with clinical history and other diagnostic tests to evaluate the allergy status accurately. The test's performance characteristics have not been reviewed or approved by the FDA, limiting its use to CLIA-certified laboratories.
