Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay, including diagnostic tests in medicine, and can be a cause of false positives. In immunology, the definition of cross-reactivity refers specifically to the reaction of the immune system to antigens. There can be cross-reactivity between the immune system and the antigens of two different pathogens, or bet… WebApr 2, 2024 · About 70 percent of sufferers of a tree pollen allergy (e.g. birch, alder, hazel) have cross-allergies, also called cross-reactions with food because their proteins are very similar.
