Culture, Exudate, Abscess, Deep Wound

Mnemonic

C EX

Synonym

Exudate Culture - Drainage Culture - Wound Culture

Includes

Gram stain, aerobic and anaerobic culture (anaerobic culture based on source/site and transport method) and susceptibility, if generally applicable

Guidelines

Preferably collect before therapy. Avoid swab collection if aspirates or biopsy samples are available. Do NOT use this order for actual pieces of tissue, see Culture, Tissue. Limit sampling to wounds that are clinically infected, chronic and nonhealing. Do not culture fresh bite wounds as they will contain respiratory organisms introduced with the bite and cannot predict cause of infection. Order AFBFungus and Virology separately.

Specimen Collection Requirements

Patient Preparation

Decontaminate site with scrub/prep. Use aseptic collection.

Collect

Use culture collection-transport swab, swab in anaerobic transport tube or pus in sterile container. Collect sample from base or advancing margin of lesion.
