Storage Instructions
Maintain specimen at room temperature.
Special Instructions
Sterile specimens (eg, sinus aspirates or tympanocentesis fluid), collected by invasive procedures, should be submitted as sterile body fluid cultures. If the amount of material aspirated is small, it may be advisable to inject it into an anaerobic transport or absorb it onto the swab of the bacterial swab collection kit and use the bacterial transport. For throat specimens submitted for isolation of Neisseria gonorrhoeae, use GC (Neisseria gonorrhoeae) Culture Only [008128] and include inoculated Jembec® transport. Specimens from other sources, such as genital, stool, urine, upper and lower respiratory specimens, cannot be cultured under the aerobic bacterial culture test number. If specimens are incorrectly submitted with an order for aerobic bacterial culture, the laboratory will process the specimen for the test based on the source listed on the test request form. The client will not be telephoned to approve this change, but the change will be indicated on the report. Check expiration date of transport; do not use expired device.
