cross reactivity
This term is used primarily in immunology and clinical diagnostics to describe a specific type of biochemical error. It occurs when the immune system or a laboratory assay fails to distinguish between two different substances because they share a similar molecular shape or epitope. This lack of specificity often results in false positive test results, which can lead to misdiagnosis in a medical setting.
In a technical context, the term is treated as an uncountable noun referring to a biological phenomenon. It is not used to describe a physical crossing of reactions, but rather the overlapping specificity of antibodies or antigens.

We must account for potential cross reactivity when designing the new assay.
Could this be a case of cross reactivity between the two viral strains?
