Adjusting the Incubation Temperature. Cross-reactivity may vary with temperature for two reasons. First, as explained above, cross-reactivity decreases with incubation time to a minimum at equilibrium. Since reaction rates increase with temperature, equilibrium is achieved more quickly at higher temperatures. 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… effect of caffeine on baby during pregnancy
