ID:627 Wound swab for bacterial culture
Search Links: General Info : Protocols : LabTestsOnline

DescriptionInfected wounds with significant surrounding cellulitis would require empirical therapy as culture results would take too long. Please follow local protocols for commencing empirical antibiotics in these scenarios or ring a medical microbiologist for advice if uncertain. With regards to sampling it is important to remove any frank pus from the surface of a wound which sometimes requires irrigation of the wound with sterile normal saline. Following that a sterile swab should be applied vigorously to the bottom of the wound or to areas which look visibly infected. This will increase the chances of isolating organisms causing infections within the soft tissue of the wound. Swabs from ulcers are discouraged. The preferred specimen from ulcers is a biopsy or aspirate. Cleaning / debridement is essential before collecting specimens from ulcers. For all wound swabs, automated liquid culture is used with manual plate reading.
