Allergen, Food, Cranberry IgE
Also known as: CRANBERRY
Use
The Allergen, Food, Cranberry IgE test is used to measure the levels of allergen-specific IgE antibodies in the blood to assess allergic sensitivity to cranberries. IgE antibodies are produced by the immune system in response to an allergen, and detecting their presence in the blood helps in evaluating allergic reactions. The test supports the diagnosis of allergies and aids allergists in understanding the patient's sensitization to cranberry allergens. However, the levels measured do not necessarily reflect the severity of symptoms when exposed to cranberries.
Special Instructions
Not provided.
Limitations
While the test measures IgE specific to cranberries, the levels of IgE do not always correlate with the clinical severity of allergic reactions or the results of skin testing. Results in the 0.10-0.34 kU/L range are particularly uncertain and should be interpreted by specialists. A negative test does not rule out cranberry allergy or the potential for anaphylaxis. Therefore, results should be correlated with clinical history and in vivo responses to the allergen.
