Test Name:
Test Code: WS, TIS
Clinical Information:
Test Indications:
Tissue (after debridement) or swabs of exudates may be submitted from burn wounds.

Culture burn wounds only after extensive cleaning and debridement. Surface cultures of burn wounds may be misleading and usually represent colonization.  Thoroughly rinse the wound with sterile saline, after debridement, prior to sample collection.  Biopsy specimens are recommended as the optimal specimen type.  For exudate submissions, collect the exudate as it appears by sampling it firmly with a swab.  Surface cultures of burn wounds may be misleading and usually represent colonization.  Samples should only be submitted for aerobic culture.

Patient Preparation Instructions:
Accurate patient identification must be made prior to sample collection.  Patient identification should be done in accordance with site policy.
Samples and requisitions must be labeled/completed in accordance with the Shared Health Specimen Acceptance Policy.  Indicate current antimicrobial therapy on the requisition.
Collection Devices:
Several drops of sterile saline should be added to tissue in the sterile specimen container if the sample cannot be delivered immediately to the lab.
Specimen Required: Tissue or exudate swab (Adult and Pediatric)
