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 adults, up to 60% of all food allergic reactions are due to cross-reactions between foods and inhalative allergens. [4] OAS is a class II allergy where the body's immune system produces IgE antibodies against pollen; in OAS, these antibodies also bind to (or cross-react with) other structurally similar proteins found in botanically related ...
People with fish allergies have a 50% likelihood of being cross reactive with another fish species, [14] but some individuals are only allergic to one species, such as; tilapia [15] salmon, [13] or cod. A proper diagnosis is considered complicated due to these cross reactivity between fish species and other seafood allergies. [16]
False positive results may be obtained due to cross-reactivity of homologous proteins or by cross-reactive carbohydrate determinants (CCDs). [6] In the NIH food guidelines issued in December 2010 it was stated that "The predictive values associated with clinical evidence of allergy for ImmunoCAP cannot be applied to other test methods."
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] ...
We support cross-Strait dialogue, and we expect cross-Strait differences to be resolved by peaceful means, free from coercion, in a manner acceptable to people on both sides of the Strait."
When in 1981 Rob Aalberse from the University of Amsterdam noticed the enormous cross-reactivity of some patients´ sera against virtually any plant and even insects, notably, insect venoms, [1] it took ten years to arrive at a possible structural explanation of this phenomenon. 1991, Japanese researchers determined the structure of the epitope common to horseradish peroxidase and Drosophila ...
Imagine stumbling out of bed and accidentally stepping on a snake. It’s the stuff of nightmares! Yet, it happens, especially in the warmer months. Snakes tend to make themselves known during ...
