YOU MAY OBTAIN A CULTURE SPECIMEN from an infected wound to identify the causative organism and help determine the most effective therapy. Use appropriate technique, usually the Z-stroke swab culturing technique shown here.

 

[black right pointing small triangle]To collect the specimen, swab the wound by gently rotating a sterile calcium alginate or rayon swab between your fingers. Swab the wound from margin to margin in a 10-point zigzag fashion. Use enough pressure to express fluid from within the wound tissue.

 

* Place the swab in the culture medium, label it according to your facility's policies and procedures, and send it to the lab as soon as possible.

 

* Redress the wound as ordered. Take off gloves and perform hand hygiene.

 

* Document the procedure, your assessment findings, and the patient's response.
