Recommendations when to order or not order the test. May include related or preferred tests.
Evaluation of IgM pertussis antibodies has little clinical utility. CDC-recommended first-line tests for pertussis are Bordetella pertussis/parapertussis by PCR (0065080) and/or Bordetella pertussis Culture (0060117).
New York DOH Approval Status
Indicates whether a test has been approved by the New York State Department of Health.
This test is not New York state approved. There are no New York state-approved laboratories available. Submit a Non-Permitted Laboratory Request Form (NPL) to the NYDOH prior to collection of specimen. If NPL is approved by NYDOH, and sample is received at ARUP, testing will be performed.
Specimen Required
Patient PreparationInstructions patient must follow before/during specimen collection.
CollectSpecimen type to collect. May include collection media, tubes, kits, etc.
Serum separator tube.
Specimen PreparationInstructions for specimen prep before/after collection and prior to transport.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 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."
Storage/Transport TemperaturePreferred temperatures for storage prior to and during shipping to ARUP. See Stability for additional info.
Refrigerated.
Unacceptable ConditionsCommon conditions under which a specimen will be rejected.
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
RemarksAdditional specimen collection, transport, or test submission information.
StabilityAcceptable times/temperatures for specimens. Times include storage and transport time to ARUP.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Expected turnaround time for a result, beginning when ARUP has received the specimen.
1-8 days
Reference Interval
Normal range/expected value(s) for a specific disease state. May also include abnormal ranges.

Components
Reference Interval
B. pertussis Ab, IgM by ELISA
1.1 IV or less
Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
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.
Component
Interpretaion
Bordetella pertussis Antibody, IgM by ELISA
0.9 IV or less: Negative - No significant level of detectable B. pertussis IgM antibody. 1.0-1.1 IV: Equivocal - Repeat testing in 10-14 days may be helpful. 1.2 IV or greater: Positive - IgM antibody to B. pertussis detected, which may indicate a current or recent exposure/immunization to B. pertussis.
Compliance Category
Laboratory Developed Test (LDT)
Note
Additional information related to the test.
If Bordetellapertussis Antibody, IgM by ELISA is 1.2 IV or greater, then Bordetellapertussis IgM Immunoblot testing will be added. Additional charges apply.
