Diagnostic modalities for infectious mononucleosis include:
Person's age, with highest risk at 10 to 30 years.

Medical history, such as close contact with other people with infectious mononucleosis, and the presence and time of onset of "mononucleosis-like symptoms" such as fever and sore throat.

Physical examination, including palpation of any enlarged lymph nodes in the neck, or enlarged spleen.

The heterophile antibody test is a screening test that gives results within a day, but has significantly less than full sensitivity (70–92%) in the first two weeks after clinical symptoms begin.

Serological tests take longer time than the heterophile antibody test, but are more accurate.
