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
Rejected Due To
- Body fluid received in Eswab
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 |
| Susceptibilities | No | No |
Reference Values
No growth
Interpretation
Positive cultures of yeast and filamentous fungi are reported with the organism identification.
Cautions
Identification was performed on the MALDI-TOF mass spectrometer biotyper. This test was developed by The Clinical Microbiology Laboratory at The Ohio State University Wexner Medical Center. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
