Specimen Requirements
Specimen must be received in laboratory within 48 hours of collection except for N. Gonorrhoeae which is 24 hours for the E Swab.
Specimen must be received in laboratory witin 24 hours for specimens received in sterile container.
Specimen source is required.
If there is a special organism(s) to be tested for, indicate on request form.
Refrigerated specimens are not suitable for isolation of Neisseria species.
Acceptable Specimens: Wound aspirate or swab, Tissue, or Body Fluid
Submit only 1 of the following specimens:
Specimen Type: Wound aspirate (preferred)
Container/Tube: Screw-capped, sterile container
Specimen Volume: Entire collection
Collection Instructions:
1. Prepare site: wash wound margins well with surgical
soap followed by 70% alcohol.
2. Aspirate deepest portion of lesion or sinus with
sterile needle and syringe or catheter.
3. Transfer aspirate to sterile container.
4. Label container with patient’s name (first and last),
medical record number, and date and actual time of collection.
Specimen should be labeled as to the specific anatomic source and
should be labeled to distinguish between “superficial”
and “deep/surgical” specimens. Do not
label only as “wound.”
For best results specimen should arrive within 1 hour of collection, unless in transport system (culturette).
Specimen Type: Wound swab (alternate)
Container/Tube: ESwab specimen collector is preferred for both aerobes and anaerobes; swab transport system (Culturette) in sterile transport tube is alternate for aerobes only.
Specimen Volume: Swab
Collection Instructions:
1. Prepare site: wash wound margins well with surgical soap followed by 70% alcohol.
2. A closed abscess is the specimen site of choice. For
most open lesions and abscesses, remove the superficial flora
by decontaminating the skin before collecting a specimen from the
advancing margin or base.
3. Pass swab into fresh purulent drainage from center of
wound, avoiding surrounding skin. It may be necessary either to
separate wound margins with thumb and forefinger of 1 hand (wearing
a sterile glove) or make a small lance in a closed abscess before
extending tip of swab deeply into wound with other hand.
4. Place swab in transport tube.
5. Label tube with patient’s name (first and last), medical record number, and date and actual time of collection. Specimens should be labeled as to the specific anatomic source and should be labeled to distinguish between “superficial” and “deep/surgical” specimens. Do not label only as “wound.”
