Broccoli, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to broccoli. It helps define the allergen responsible for causing allergic reactions and is useful in identifying allergens that contribute to allergic responses and/or anaphylactic episodes. Additionally, it confirms sensitization prior to immunotherapy and investigates specific allergic reactions to various allergens including insect venom, drugs, or chemicals. Testing for IgE antibodies is not recommended for patients who have undergone immunotherapy to determine residual sensitivity, or when allergen specificity does not impact medical management.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not beneficial for patients previously treated with immunotherapy for assessing residual clinical sensitivity. The test might not be useful if the identification of allergen specificity does not guide medical management. False positives can occur in patients with high serum IgE levels due to nonspecific binding.
