Oral Food Challenges & Relationship to Allergen-Specific IgE Levels

Diagnosis of food hypersensitivity is a clinical challenge and the only current definitive test is the Double Blind Placebo-Controlled Food Challenges. Although the Double Blind Placebo-Controlled Food Challenges is the current gold standard, it is difficult to perform and is very time-consuming. Hence, researchers are continually evaluating new tests and assessing the value of the available serum tests. (more…)

Food Allergy Testing by Performing Allergy Skin Test and In Vitro Test

allergy skin testing
The diagnostic approach to allergic food reactions comprises three steps. The first step includes the medical allergy history, physical examination, and family allergy background. On the basis of symptoms and timing of the reaction, the physician attempts to identify the suspected food and to determine whether the reaction is likely to involve an immunologic mechanism. This first step is absolutely necessary to decide on the subsequent diagnostic tests to be performed. The second step includes allergy skin tests and in vitro assays, which can confirm a sensitization to the food. (more…)
