Ordering RecommendationRecommendations when to order or not order the test. May include related or preferred tests.
If serology is used to assess late-stage pertussis (>4 weeks), the recommended test is Bordetella pertussis Antibodies, IgA and IgG by ELISA with Reflex to Immunoblot (2001774). CDC-recommended first-line tests for pertussis are Bordetella pertussis/parapertussis by PCR (0065080) and/or Bordetella pertussis Culture (0060117).

Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
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.
