Allergen, Food, Coconut
Also known as: COCONUT
Use
This test is used to detect IgE antibodies specific to coconut allergens. It aids in the diagnosis of food allergies to coconut, allowing healthcare providers to assess patients' risk of allergic reactions upon exposure. The presence of IgE antibodies suggests a sensitization to coconut, which may be correlated with clinical symptoms when ingested or in contact with this allergen.
Special Instructions
Multiple patient encounters should be avoided to prevent erroneous increases in allergen levels. Ensure proper collection and handling of serum samples to avoid specimen degradation which may affect test results. For multiple allergen orders, refer to the Allergen Specimen Collection Instructions on the ARUP website.
Limitations
IgE levels detected by this test may not correlate with the severity of allergic reactions. The test should be interpreted in the context of clinical history and other allergy testing methods. False negatives may occur, failing to rule out potential coconut allergies, and the presence of other cross-reactive allergens should be considered. The concentrations may not correlate with the degree of clinical response.
