How is pertussis diagnosed?
Pertussis is usually diagnosed by a doctor, based on history of symptoms, a physical examination, and supporting laboratory tests. Two common lab procedures used are culture tests using bacteria specimens taken from the nose or throat and blood tests. Laboratory tests are often necessary for pertussis because other germs can produce somewhat similar symptoms.
