Aspirate from collection, abscess or wound; biopsy of abscess wall. The specimen should be collected in a sterile container. It is also possible to send a capped syringe (needle must be removed).

Pus should always be aspirated, if possible, rather than collecting a wound swab.

Swabs from a draining wound or sinus are frequently contaminated with normal flora from skin, mucous membrane.

Pus should be transported immediately to the laboratory.

Biopsy of abscess wall or adjacent tissue may increase the yield, especially in chronic infection.
