• Reference Range:
  

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

  Bordetella pertussis Antibody, IgA by Immunoblot
  Negative

  Bordetella pertussis Antibody, IgG by ELISA
  0.9 U/mL or less: Negative - No significant level of detectable Bordetella pertussis IgG antibody.
  1.0-2.4 U/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
  2.5 U/mL or greater: Positive - IgG antibody to Bordetella pertussis detected, which may indicate a current or past exposure/immunization to B. pertussis.

  Bordetella pertussis Antibody, IgG by Immunoblot
  Negative

  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, IgA by ELISA is 1.2 U/mL or greater, then Bordetella pertussis IgA Immunoblot testing will be added; if Bordetella pertussis Antibody, IgG by ELISA is 2.5 U/mL or greater, then Bordetella pertussis IgG Immunoblot testing will be added; 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.
