  • Reference Range:

    Bordetella pertussis Antibody, IgM by ELISA
    0.9 U/mL or less: Negative - No significant level of detectable Bordetella pertussis IgM antibody.
    1.0-1.1 U/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
    1.2 U/mL or greater: Positive - IgM antibody to Bordetella pertussis detected, which may indicate a current or recent exposure/immunization to B. pertussis.

    Bordetella pertussis Antibody, IgM by Immunoblot
    Negative

    Interpretive Data:
    Recommend that treatment decisions be based on the result of the B. pertussis IgM immunoblot test instead of the ELISA test. B. pertussis IgM test by ELISA may produce false-positive results.

    Note:
    If Bordetella pertussis Antibody, IgM by ELISA is 1.2 U/mL or greater, then Bordetella pertussis IgM Immunoblot testing will be added. Additional charges apply.
