87071 (culture); 87205 (Gram stain)
Test includes a direct Gram stain, isolation and identification of microorganisms, and susceptibility testing, if appropriate. Other isolated organisms (i.e. fungi, mycobacteria) may be referred for identification and/or susceptibility testing if medically indicated AND a separate culture procedure has NOT yielded the same organism(s).
Daily, 24 hours
Gram stain: 1 hour for CSF after receipt of the specimen in the laboratory. Preliminary culture reports available after 24 hours. Culture reports of no growth will be issued after 72 hours. Completion of culture reports may take 3-4 days after receipt of the specimen when multiple isolates are found.
The specific anatomic site of the body fluid MUST be specified on the order or the requisition. All sterile body fluids (except CSF) cultured aerobically and anaerobically unless specifically indicated on the order or requisition that "no anaerobic culture needed."
The specimen of choice is an aspirate, NOT a swab. Specimens are to be collected from a site prepared utilizing aseptic technique. Overlying and adjacent areas must be carefully prepared to eliminate surface (normal flora) organisms. Ideally, material obtained by needle aspiration through intact surface which has been cleaned with antiseptic, is put directly into a sealed, sterile container. Swabs should be used as a last resort due to the small volume of specimen obtainable by this method. If a swab must be used, use the Copan Swab® II collection device. Contamination with normal flora from skin or other body surfaces must be avoided since colonizing bacteria not involved in the infectious process may be introduced into the sample. Pulmonary samples may be obtained by transtracheal percutaneous needle aspiration.
1 mL sealed sterile container, 0.5 mL per Bact/Alert bottle
Specimen should be transported as soon as possible. When transportation is delayed, leave at room temperature. Do NOT refrigerate.
LIMITATIONS OF TEST:
The use of blood culture bottles for submission of the specimen has some limitations: quantitation unavailable, Gram stain unavailable unless a separate sample is submitted. Use of the blood culture bottles does however increase the sensitivity of the culture procedure.
Inoculation of conventional culture media; automation (continuous monitoring) for Bact/Alert blood culture media.
