Package of tests for Pertussis - (Bordetella pertussis IgA, IgG, IgM).

Testing the level of IgA, IgG, IgM antibodies against Bordetella pertussis in the blood.

Determination of IgA, IgG, IgM antibody levels is used in the diagnosis of pertussis. Pertussis, otherwise known as whooping cough, caused by the bacterium Bordatella pertussis, is an infectious disease that takes the form of chronic bronchitis with severe coughing attacks. The level of IgA, IgG, IgM antibodies increases in the second week of symptomatic illness.

IgA, IgG, IgM antibodies persist for 2-3 months, after which they disappear. Elevated titers of IgA, IgG, IgM antibodies are indicative of fresh pertussis infection, only in unvaccinated individuals or in those whoóve received their last dose of pertussis vaccine several years ago or earlier.

The titer of IgA, IgG, IgM antibodies is not as high as that of IgA, IgG, IgM antibodies.
