Allergen, Food, Codfish IgE
Also known as: COD
Use
The Allergen, Food, Codfish IgE test is used to measure the level of IgE antibodies specific to codfish in the patient's blood. This test aids in the diagnosis of a codfish allergy, which can trigger symptoms ranging from mild reactions such as hives and gastrointestinal issues to more severe reactions like anaphylaxis. The interpretation of allergen-specific IgE levels should be integrated with clinical history and other diagnostic evaluations, as IgE levels alone may not correlate with the severity of allergic reactions.
Special Instructions
Patients should avoid multiple medical encounters as much as possible. Serum must be separated from cells promptly, ideally within two hours of collection, and transferred to an ARUP Standard Transport Tube. Ensure the appropriate volume is collected for multiple allergen tests and refer to ARUP's Allergen Specimen Collection Instructions for more details.
Limitations
Allergen-specific IgE concentrations, although indicative, do not definitively predict clinical allergic reactions or skin test results upon exposure to the allergen. A negative result does not exclude the possibility of a clinically significant allergy. This test's outcomes require correlation with patient history and other allergy evaluations, as results in the range of 0.10-0.34 kU/L particularly, may hold undetermined clinical significance.
