Question

Quizplus · Accepted Answer

The correct answer is indirect agglutination reaction. In this method, anti-HCG antibodies are attached to latex spheres. When a woman's urine containing HCG is added, it binds to the anti-HCG on the spheres, causing them to clump together (agglutinate), indicating a positive pregnancy test. This is an example of an indirect agglutination reaction because it involves the use of particles (latex spheres) coated with antibodies to detect the presence of antigens (HCG).
