Place swab in tube containing transport medium, e.g. “Transwab”. Swabs that are not sent to the laboratory immediately can be stored at room temperature for up to 24 hours.
For the diagnosis of Pertussis pernasal swabs are available and are preferred to cough plates. Swabs should arrive (by arrangement with the laboratory) within half an hour of being taken, as the causative organism is particularly fastidious.
Swabs should be submitted in Chlamydia transport medium for PCR investigation.
