Test Code FBCUL 
Test CULTURE, FUNGUS, BLOOD 
Methodology Bactec 9000® / Blind Subcultures
Includes "Culture, Bacteria, Blood." 
Description Fungal Isolates reflex to organism identification. Bacterial isolates reflex to organism identification and antibiotic susceptibility test. Additional charges apply. 
Specimen Collect specimen using the following procedure:
1. Remove plastic caps from Bactec® blood culture bottles and place an alcohol prep on top of the exposed rubber. DO NOT USE BETADINE.
2. Apply tourniquet and locate the vein. Release the tourniquet during skin preparation.
3. Hold Mediflex® Frepp® sponge (70% isopropyl alcohol) in a horizontal position and pinch handle once to break ampoule. Do not continue to squeeze handle. Place sponge on venipuncture site and depress once or twice to saturate sponge. Scrub vigorously for 60 seconds and allow to dry.
4. Hold Mediflex® Sepp® ampoule (2% iodine tincture) in downward position and pinch center of Sepp® to crush ampoule. Apply to venipuncture site starting at the center and moving outward in concentric circles.
5. Allow the prepared site to air dry at least 30 seconds. This will ensure that the iodine is allowed adequate time to disinfect the skin.
6. Re-apply the tourniquet.
7. Do not repalpate or touch the venipuncture site after it has been prepared.
8. Perform venipuncture using aseptic technique and a sterile syringe with an adequately gauged needle. The recommended draw for a single blood culture follows:

Patient Age Amount of Blood
< 12 months ------- 2 - 3 mL
12 - 24 months ---- 3 - 5 mL
2 - 9 years --------- 5 - 8 mL
>= 10 years ------ 16 - 20 mL

9. Release tourniquet.
10. Withdraw needle.
11. Apply gauze. Do not allow gauze to touch needle during withdrawal.
12. Apply pressure to puncture site.
13. Inoculate appropriate bottles with volumes listed in the following table. It is not necessary to change needles between collection and inoculation.

Amount of Blood = > 10 mL:
Anaerobic Bottle - Half
Aerobic Bottle - Half

Amount of Blood = 5 - 10 mL:
Aerobic Bottle - All

Amount of Blood = < 5 mL:
Pediatric Bottle - All


14. Using an alcohol swab, thoroughly clean all vial tops following inoculation of specimen.
15. Label bottles with patient's name (first and last), date of birth or medical record number, date and time of collection, collector's initials and specimen source.
