ristireagoinnin
Ristireagoinnin is a Finnish term that translates to "cross-reaction" or "cross-reactivity" in English. It refers to a phenomenon in immunology and analytical chemistry where a molecule or substance, such as an antibody or a primer, binds to or interacts with a target that is not its intended or primary target. This can occur due to structural similarities between the intended target and the unintended cross-reactive substance.
In the context of medical diagnostics, cross-reactivity can lead to false positive results. For example, if
Researchers and diagnosticians work to minimize cross-reactivity by designing highly specific antibodies, primers, and other reagents.
