Answer:
In the context of infectious mononucleosis, the presence of heterophile antibodies can be detected through the Paul-Bunnell test. These antibodies are produced in response to infection with the Epstein-Barr virus, which is commonly associated with mononucleosis.
When an 18-year-old girl has infectious mononucleosis, the expected Heterophile Antibody result would be:
b. No agglutination with horse RBC's.
Explanation:
Heterophile antibodies are antibodies that can agglutinate (clump together) red blood cells from different species, such as horse RBCs. In the presence of infectious mononucleosis, these antibodies are produced and can cause agglutination specifically with horse RBCs. Therefore, the absence of agglutination with horse RBCs would indicate a positive result for heterophile antibodies, which is characteristic of infectious mononucleosis.
