EPIC: LAB5511, SOFT: CXWNS
Department
Microbiology
Instructions
- Wound, Superficial is defined as a wound in the skin or infected space that may drain through the skin and that does not extend deeper than the dermis.
- Only an aerobic culture is included as part of this test.
- For specimens from wounds that penetrate deeper than the dermis, please refer to Culture, Wound - Deep.
- For tissue specimens, please refer to Culture, Tissue.
- For surgical specimens, please refer to Culture, Surgical.
- For fluid specimens obtained from a sterile site, please refer to Culture, Fluid.
Specimen Collection Criteria
Tissue or fluid is always superior to a swab specimen.
Collect: One of the following specimens:
- (Preferred) Fluid specimen in a sterile collection container or sterile sealed syringe (without the needle). Do NOT submit the syringe with the needle attached.
- (Alternate) Specimen collected with an ESwab.
Physician Office/Draw Specimen Preparation
Place specimens in a transport system immediately and maintain at room temperature (20-26°C or 68-78.8°F) prior to transport. Do not refrigerate the specimen.
Preparation for Courier Transport
Transport: Specimen in a sterile collection container or an ESwab, at room temperature (20-26°C or 68-78.8°F).
Rejection Criteria
- Specimens submitted in a container with formalin or that has ever contained formalin.
- Specimens in non-sterile or leaking containers.
- Desiccated (dry) samples.
Inpatient Specimen Preparation
Transport specimen to the Laboratory immediately after collection.
Storage
Specimen Stability for Testing:
Room Temperature (20-26°C or 68-78.8°F): 4 hours (Not in transport system)
Room Temperature (20-26°C or 68-78.8°F): 24 hours (In transport system)
Refrigerated (2-8°C or 36-46°F): Unacceptable for genital sources
Frozen (-20°C/-4°F or below): Unacceptable
Specimen Storage in Department Prior to Disposal:
Refrigerated (2-8°C or 36-46°F): 4 days
Room Temperature (20-26°C or 68-78.8°F) – Genital sources: 7 days
Laboratory
Royal Oak Microbiology Laboratory
Farmington Hills, Grosse Pointe, and Troy sent to Royal Oak Microbiology Laboratory for testing.
Dearborn Microbiology Laboratory
Taylor, Trenton and Wayne sent to Dearborn Microbiology Laboratory for testing.
Performed
Sunday – Saturday, 24 hours a day.
Preliminary results available within 24 hours.
Reference Range
Skin microbiota may be isolated.
Test Methodology
Gram stain, aerobic culture, identification and susceptibility testing (if indicated).
Interpretation
The recovery of aerobic bacteria from an appropriate, properly collected specimen may be indicative of an infectious disease process.
Reflex Testing
Mold obtained from bacterial cultures will be reflexed to the Mycology Laboratory for identification (sterile sites only).
Clinical Utility
This test is used to recover and identify aerobic bacteria that may be involved in human infections.
