Test Code ANCOMBO Culture, Aerobic and Anaerobic
Methodology
Conventional Culture Technique
Includes Gram stain.
Note: 1. If 1 or more aerobic pathogens are
isolated, antibiotic sensitivities (minimum inhibitory
concentration) will be performed at an additional charge for each
pathogen.
2. No antibiotic sensitivities are performed for anaerobic organisms.
Performing Laboratory
Aspen Valley Hospital
Specimen Requirements
An aerobic and an anaerobic specimen are required for this test.
Aerobic Culture
Specimen must arrive within 48 hours of collection.
Submit only 1 of the following specimens:
Acceptable Specimens:
Abscess, body fluid, decubitis exudate, deep wound, percutaneous
transtracheal aspirate, pilonidal abscess, single-channel
bronchoscope, or urine (suprapubic aspirate or bladder
aspirate only)
1. Aseptically collect specimen from where suspected organism will most likely be found using eSwab culturette.
2. Return swab to sterile culture transport tube to ensure specimen preservation.
3. Label tube with patient’s name (first and last), date and actual time of collection, and type of specimen.
4. Maintain sterility and forward promptly at ambient temperature only.
Note: 1. If fastidious bacteria such as Neisseria gonorrhoeae or Streptococcus pneumoniae is suspected, specimen should arrive within ≤24 hours of collection.
2. Collect before start of antibiotic therapy whenever possible.
3. Specimen source is required on request form for processing.
Anaerobic Culture
Specimen must arrive within 18 hours of collection for plating on appropriate media.
Submit only 1 of the following specimens:
Acceptable Specimens:
Abscess, body fluid, deep wound, or percutaneous transtracheal
aspirate
Unacceptable Specimens:
Cervical, colostomy drainage, decubitis exudate, feces, gastric,
gingival, nasopharyngeal, perirectal abscess, pilonidal abscess,
single-channel bronchoscope, sputum, superficial wound, throat,
urine, or vaginal
1. Aseptically collect specimen from where suspected organism will most likely be found.
2. Place specimen in anaerobic transport medium
supplied from Nursing Unit Pyxis or Laboratory for Outreach
Offices. (Specimen submitted in non-sterile
container or specimen delayed >20 minutes [unless
collected in Anaerobic Transport Media] is not
acceptable.)
3. Label specimen with patient’s name (first and last),
date and actual time of collection, and type of specimen.
4. Forward promptly at ambient temperature only. Do not
refrigerate.
Note: 1. Collect before start of
antibiotic therapy whenever possible.
2. Specimen source is required on request form for processing.
