A blocking antibody is an antibody that does not have a reaction when combined with an antigen, but prevents other antibodies from combining with that antigen.^[1]

The term can also be used for inhibiting antibody, prozone phenomenon and, agglutination reaction.

Blocking antibodies have been described as a mechanism for HSV-1 to evade the immune system.^[2]
