What type of test is Paul Bunnell test?

Heterophil antibody tests such as the Paul Bunnell or Monospot tests may be used in the diagnosis of glandular fever. Heterophil antibodies have the ability to agglutinate red blood cells of different animal species. The Paul-Bunnell test uses sheep erythrocytes; the Monospot test, horse red cells.

How do you perform a Monospot test?

A sample of blood is placed on a microscope slide and mixed with other substances. If heterophil antibodies are present, the blood clumps (agglutinates). This result usually indicates a mono infection. Monospot testing can usually detect antibodies 2 to 9 weeks after a person is infected.
