The mononucleosis test is specifically designed to detect heterophile antibodies, which are antibodies that are produced in response to certain infections, most notably infectious mononucleosis, commonly caused by Epstein-Barr virus (EBV). During the infection, the body's immune system reacts by producing these heterophile antibodies.

The test involves the agglutination of red blood cells from other species (often sheep) in the presence of these antibodies, indicating a positive result for the presence of infectious mononucleosis. This test is quick and relatively easy to perform, making it a common tool for clinicians when assessing patients who present with symptoms of mononucleosis, such as fever, sore throat, and lymphadenopathy.

Other tests listed have different specific purposes. The Coombs test is used to detect antibodies that act against the surface of red blood cells, commonly in cases of hemolytic anemia. The ELISA test (Enzyme-Linked Immunosorbent Assay) is a broader immunological test used for various infections and diseases by measuring specific antibodies or antigens. The Western blot is a technique used primarily to detect specific proteins in a sample, often used as a confirmation test for HIV but not specifically for heterophile antibodies. Thus
