Test ID: FBDP    
Bordetella pertussis IgG Antibodies, MAID

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Reference Ranges:

    PT IgG       <45 IU/mL

    FHA IgG    <90 IU/mL

Levels of antibodies recognizing pertussis toxin (PT) and filamentous hemagglutinin antigen (FHA) are typically increased following either vaccination or natural exposure to Bordetella pertussis. Increased levels of FHA IgG alone may represent crossreactive antibodies induced by infection with other Bordetella species, Mycoplasma pneumoniae, Chlamydia pneumoniae, or nonencapsulated Haemophilus influenzae.
