Sample Requirements
Specimen: BD ESwab, Tissue sample, or piece of hardware.
Container: ESwab should be inserted into the tube of Aimes transport media that is provided in the swab collection kit. Tissue or hardware should be placed into sterile container.
Preferred Vol: N/A
Minimum Vol: N/A
Please consult the Photo Swab Guide to determine which swab to collect.
Main Campus collection: Sample should be collected on a BD ESwab, in a sterile syringe, or sterile cup (for larger volumes) . Note that the BD ESwab (available from Central Service and Demand Flow carts) are acceptable for both culture and Gram stain.
Regional Clinic Collection: Samples collected at Regional Clinic locations (where specimen set up will be delayed) are optimally collected on a BD ESwab Amies transport media. Samples collected on ESwabs swabs can also be used for Gram Stain and are stable at room temperature for up to 24 hours for transport to SCH.
Sterile fluid samples from hardware sites can be collected in a syringe or sterile cup.
Tissue samples or Hardware samples should be collected into a sterile container.
Processing Instructions
CPA: Send sample to Microbiology for processing. If the sample is shared and only one tube, syringe or other container is received, affix shared sample label and send entire sample plus requisition to Microbiology.
Regional Clinic collection: Samples collected on BD ESwabs are sent to Main Campus Microbiology for culture set up. Swabs should be retained at room temperature until and during courier transport.
Fluid sent in a capped syringe should be set up at the Off-site Labs per Lucidoc instructions. After set up, refrigerate remaining sample. Incubate plates until courier transport.
Tissue sent in sterile container should be sent via cab to SCH Micro for immediate culture set up. Overlay large tissue pieces with Thio broth to keep tissue moist.
Note: If the tissue piece is small it can be placed in an ESwab Transport media tube. This tube can then be kept at room temperature until courier pick up.

87205 (Gram Stain)
This test is not limited to the CPT codes listed. Others may be added as more testing is necessary and depending on the pathogens isolated (such as MIC's and ID's)
Description
Includes Bacterial Culture and Gram Stain. Specimen is cultured for Aerobic and Anaerobic bacteria. This culture type is held for 14 days to allow cultivation of fastidious and/or slow growing organisms that are often associated with hardware infections (ex: Cutibacterium).
Reporting Information
Preliminary Report: 18 - 24 hours
Negative Final Report: 14 days
Broth culture incubation is automatically extended up to 14 days for Hardware Associated Wound Cultures.
