Test Code MIC3 Anaerobe Culture

Clinical Information

Diagnosing anaerobic bacterial infections.

Synonym

  • ANACX

Specimen Required

Preferred Container/Tube: Sterile Container
Acceptable Container/Tube: eSwab, Sterile Container

Specimen Source: Sterile body fluids, deep abscess content, deep wound aspirates, suprapubic urine aspirates, kidney aspirates, lung tissue or aspirates, sinus tissue or aspirates
Specimen Volume: Fluids 1 mL, Tissues 5 mm

If limited specimen is received, tests will be processed in the following order of priority. Tests unable to be processed will be canceled. 
                  1. Aerobic culture
                  2. Anaerobic culture
                  3. Fungal culture

Specimen Collection Information

Transport specimen to laboratory as soon as possible.

Fresh tissue (5–10 mm) or body fluid (1–1.5 mL) should be collected for microbial culture. E-swab specimens are acceptable only for tissue collection when biopsy is not feasible. They must not be used for body fluid collection under any circumstances. All body fluid specimens must be submitted in sterile, leak-proof containers. A separate tissue or body fluid specimen must be submitted for mycobacterial culture, as it requires distinct handling and processing protocols.

Fine needle aspiration (FNA) yields limited material and may not meet the minimum tissue volume (5–10 mm) required for optimal culture sensitivity. Core needle biopsy is preferred for microbiologic evaluation of deep tissue infections.

Bone samples frequently arrive as small fragments. While acceptable, larger tissue pieces (≥5 mm) enhance sensitivity and improve pathogen recovery.

Specimen Stability Information

Ambient:
     Sterile Container: 24 hours
     eSwab: 2 days

Testing Algorithm

When this test is ordered, the reflex tests may be performed at an additional charge.

Reflex Test

Reporting Name Available Separately Always Performed
MALDI-TOF No No

Reference Values

No growth

Cautions

Specimens should be collected by needle and syringe aspiration or surgical drainage to avoid contamination with normal-flora anaerobes.
