The initial diagnosis is usually based on the symptoms. However, when the symptoms are not obvious, pertussis may be difficult to diagnose. In very young infants, the symptoms may be caused by pneumomnia instead.

To know for sure, the health care provider may take a sampleofmucus from the nose nasal secretions and send it to a lab, which tests itfor pertussis. While this can offer an accurate diagnosis, the test some time, and treatment is usually started before the results are ready.

Some patients may have a complete blood count that shows large numbers of lymphocytes.
