Affixing Antigen to an Inert Particle Such as a Latex

Question

Affixing antigen to an inert particle such as a latex bead is sometimes used in which type of test?
A)cross-reactions
B)agglutination
C)precipitation
D)specificity
E)sensitivity

Accepted Answer

Affixing antigen to a latex bead is commonly used in agglutination tests. In these tests, antibodies present in a patient's serum will bind to the antigen-coated latex beads, causing them to clump together or "agglutinate." This can be used to detect the presence of specific antibodies in a patient's blood, which can be helpful in diagnosing infections or other diseases.
