The SERION ELISA classic Bordetella pertussis Toxin IgG and IgA tests are qualitative and quantitative immunoassays for the detection of human antibodies in serum or plasma directed against Bordetella pertussis Toxin.

The assays serve to demonstrate contact with the pathogen and can be used, in combination with the SERION ELISA classic Bordetella pertussis IgA, IgG and IgM tests, for the differential diagnosis of pneumonia.
