Reference Interval:
Negative: Less than 0.9 IV

Interpretive Data:
A positive result, with consistent clinical symptoms and history, suggests an acute or recent B. pertussis infection.  A positive result may also result from vaccine antibodies.  This assay cannot differentiate between vaccine antibodies and antibodies from an infection; however, a positive result of greater than 1.8 IV suggests an acute infection if vaccination occurred at least 12 months prior to testing.

Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory.
