Guar Bean Gum (f246) IgE

Test Summary

This test is an allergen-specific IgE antibody test that quantifies an individual’s IgE response to guar gum. It is an in vitro quantitative assay, which is intended to be used in conjunction with other clinical information to aid in the diagnosis of food Used to detect possible allergic responses to various substances in the environment [1].

While allergen-specific serum IgE testing is considered comparable to skin testing in many instances, both the American Academy of Used to detect possible allergic responses to various substances in the environment, Asthma, and Immunology and the American College of Used to detect possible allergic responses to various substances in the environment, Asthma, and Immunology recognize that allergen-specific serum IgE testing may be preferred in some clinical situations. These include 1) the presence of widespread skin disease, 2) the recent use of antihistamines or other medications that can affect the results of Used to detect possible allergic responses to various substances in the environment skin tests, 3) uncooperative patients, and 4) medical history suggesting that allergen skin testing would pose a significant risk for a serious allergic reaction [1].

Food-specific IgE tests are extremely sensitive. However, a positive test result only indicates that a patient is IgE sensitized to the food of concern. Many IgE-sensitized patients do not develop any symptoms when this food is ingested. A diagnosis of food Used to detect possible allergic responses to various substances in the environment should only be made by a trained medical provider, after conducting a thorough clinical evaluation [2,3]. While food-specific IgE test results may contribute to that evaluation, they cannot replace it. In this regard, detection of food-specific IgE in serum provides evidence of IgE sensitization, but a history of clinical reactivity to the food of concern, is required to make a diagnosis of IgE-mediated food Used to detect possible allergic responses to various substances in the environment. Moreover, several forms of food hypersensitivity are not associated with the presence of food-specific IgE in serum.
