Heterophile antibodies can cause significant interference in any immunoassay. The presence of a heterophile antibody is characterized by broad reactivity with antibodies of other animal species (which are often the source of the assay antibodies).

For several weeks to months after acute onset of the infection, it is spread by upper respiratory secretions that contain the virus.
