Introduction to Serology and Immunoassays Quiz

To study the presence or concentration of molecules (antigen/antibody) in a solution using antibodies/antigens.

Immunoassays focus on the presence or concentration of molecules in a solution, while serology studies the presence of infection and other diseases by detecting antibodies/antigens in blood/plasma/serum.

Agglutination, Enzyme immunoassays (ELISA), Lateral flow Immunoassay, Fluorescence immunoassays (Flow Cytometry).

<p>Antibodies are used to detect antigens, and antigens are used to detect antibodies, based on the specificity of the interaction between antigen and antibody.</p> Signup and view all the answers
