Other Diagnostic Studies

  • Polymerase chain reaction (PCR)
    • PCR has excellent sensitivity and can be performed rapidly.[1]
    • PCR is most accurately performed within 4 weeks of cough onset; performed post 4-weeks greatly raises the chance of false-negative readings.[1]
  • Direct fluorescent antibody (DFA) testing
    • DFA's positives include inexpensive cost and rapid results.[2]
    • DFA's drawbacks include poor sensitivity and specificity.[2]
  • Pulsed-field gel electrophoresis (PFGE)
