Pus and or drainage collected in Sterile, no additive, leakproof, leakproof container or needle aspirate are preferred. (Swabs are not optimal) 

Decontaminate the skin surface, collect purulent material aseptically from undrained abscesses using a sterile needle and syringe. Alternately, open abscess with scalpel and collect expressed material with syringe or swab. Open wounds will require proper cleansing with removal of scab or existing exudate and the collection of tissue from the leading edge of the wound.
