The original serologic test for infectious mononucleosis, the Paul-Bunnell test, detected heterophile antibodies by agglutination of sheep or horse red blood cells.18 Later, guinea pig kidney absorption of serum was added to increase the specificity of the test.19 These tests are now available in convenient latex agglutination or solid-phase immunoassay form.
