Reference Range:
Bordetella pertussis Antibody, IgG by ELISA with Reflex to Immunoblot Bordetella pertussis Antibody, IgG by ELISA 0.0-0.9 U/mL Bordetella pertussis Antibody, IgG by Immunoblot Refer to report Bordetella pertussis Antibody, IgM by ELISA with Reflex to Immunoblot 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 Refer to report
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.
