Bordetella pertussis Antibodies, IgA and IgG by ELISA with Reflex to Immunoblot
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Qualitative Immunoblot
New York DOH Approval Status
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL) Parallel testing is preferred, and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|B. pertussis Ab, IgA by ELISA||1.1 IV or less|
|B. pertussis Ab, IgG by ELISA||1.04 IV or less|
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
|Bordetella pertussis Antibody, IgA by ELISA||0.9 IV or less: Negative - No significant level of detectable Bordetella pertussis IgA antibody.
1.0-1.1 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.2 IV or greater: Positive - IgA antibody to Bordetella pertussis detected, which may indicate a current or past exposure/immunization to B. pertussis.
|Bordetella pertussis Antibody IgG by ELISA||0.94 IV or less: Negative - No significant level of detectable B. pertussis IgG antibody.
0.95-1.04 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.05 IV or greater: Positive - IgG antibody to B. pertussis detected, which may indicate a current or recent exposure/immunization to B. pertussis.
Laboratory Developed Test (LDT)
If Bordetella pertussis Antibody, IgA by ELISA is 1.2 IV or greater, then Bordetella pertussis IgA Immunoblot testing will be added; if Bordetella pertussis Antibody, IgG by ELISA is 1.05 IV or greater, then Bordetella pertussis IgG Immunoblot testing will be added. Additional charges apply.
