This is a specialized medical and immunological term. It is used to describe a specific class of antibodies detected in diagnostic tests. * The presence of a heterophile antibody is a key indicator for diagnosing infectious mononucleosis. * The test for heterophile antibody is often called the monospot test.
- Heterophile Antibody Interference: In clinical laboratory science, this refers to a false result in an immunoassay caused by the presence of these antibodies, which can bind to reagent antibodies and disrupt the test.
- The unexpected test result was attributed to heterophile antibody interference.
- Heterophile (adjective): Pertaining to or being a heterophile antibody.
- The patient had a positive heterophile test result.
- Paul-Bunnell Antibody: A historical synonym for the heterophile antibody associated with mononucleosis, named after its discoverers.
