Blood Culture, Aerobic


Sunquest Code:BC  
Epic Code:LAB462Epic Name:Blood Culture
Synonyms:BCX; Blood CX; B CX
Methodology:Bac T Alert culture method (fluorescence)-FRMC. BACTEC culture method (fluorescence)-UMMC, FSH, FRH,FLH, FNH
CPT Code:----------CPTCODES HERE----------
Test Includes:Culture for aerobes, anaerobes (see below).
Turnaround Time:Performed 24 hours/day; preliminary reports are issued at 24 hours. Care provider is contacted when culture is positive; negative results are reported within 6 days.
Special Instructions:

Previous antimicrobial therapy may delay the growth of organisms but does not warrant additional cultures. Note if blood specimen is collected through a vascular access device to aid in interpretation of positive results.

 

Aerobic and anaerobic culture bottles are always drawn together at UMMC-Riverside, FSH, FRH and FRMC. These sites do not need to request an anaerobic collection.

Collection Instructions

Specimen:Blood
Optimal Volume:Adult: 8-10 mL, 3mL minimum, in BACTEC Plus Aerobic/F
Minimum\Peds Volume:Pediatric: 3 mL, 1 mL minimum in BACTEC Peds Plus/F
Collection Instructions:
See Blood Collection for Cultures (Bacterial, Fungal, Viral) under Laboratory Procedures.  
  • FUO, acute or subacute bacterial endocarditis: Obtain three blood cultures on the first day, at least 10 minutes apart. If negative after 24 hours, collect two or three more. If five to seven blood cultures are negative, consult the Microbiology Laboratory and Infectious Disease. Special culture techniques may be useful. Indicate if endocarditis is suspected on request form.

  • Anaerobic blood culture is only collected when specifically requested. Previous antimicrobial therapy may delay the growth of organisms but does not warrant additional cultures. Note if blood specimen is collected through a vascular access device to aid in interpretation of positive results.
