Whooping Cough Immunity Test - Bordetella Pertussis Antibodies (IgG & IgA) Test

Two separate serological tests are used to determine the titers of immunoglobulin G (IgG) and immunoglobulin A (IgA) antibodies against Bordetella pertussis, the bacterium that causes whooping cough. These tests are used to measure the immune response after natural infection or vaccination, and to help diagnose infection in adolescents and adults, where symptoms are often atypical.
