Order: 

If yeast or fungus is suspected, see Blood Culture/Fungus. If Mycobacteremia (AFB/TB) is suspected, see Blood Culture/Acid Fast Organisms.

Specimen:  

Specimens must be collected using sterile techniques.

• Cleanse site with 70% isopropyl alcohol, followed by a 2 minute scrub with 2% tinctures of iodine solution.
• Remove & discard the plastic cover(s) from the culture bottle.
• Disinfect the rubber septum of each bottle with a 70% alcohol pad or iodine. 
• Do not touch venipuncture site.  Use a syringe or BacTALERT Blood Collection Adapter set to obtain the blood cultures.  Draw 1-4 ml for pediatric patients <5 yrs old.  Draw 20 ml for all others.
• For syringe draws only: Place a new needle on the syringe.  Put blood into blood culture bottles, using the following procedure:

Pediatric (<5yrs): Inject 1-4 ml whole blood into the BacTALERT Pediatric PF bottle (yellow) Avoid injecting air into the bottle.  Invert to mix. Patients > 5 yrs old: Draw 20 ml blood. Inject 10 ml blood into the aerobic bottle (green) and 10 ml of whole blood into the anaerobic bottle (purple)  Avoid injecting air into the bottles.  Invert to mix.

• If the BacTALERT Blood Collection Adapter set is used, collect 4ml of blood into the Pediatric PF bottle (yellow) OR 10ml of blood into each of the aerobic (green) and anaerobic (purple) bottles.

Comments:

• A minimum of two sets of blood cultures within a 24 hour period is recommended.
• Culture is tested daily by continuous monitoring technology.
• Culture detects both aerobic and anaerobic bacteria.
• The aerobic and pediatric bottles contain activated charcoal which will aid in the recovery of organisms if antimicrobial therapy was initiated before the culture was obtained.
• ALL POSITIVE BLOOD CULTURE RESULTS WILL BE PHONED TO THE PHYSICIAN, NURSING PERSONNEL OR ORDERING LOCATION RESPONSIBLE FOR THE PATIENT.
• Susceptibility testing will routinely be performed on ALL aerobic isolates. (EXCEPT diphtheroids, Bacillus species, Viridans Streptococcus and Micrococcus species).

RL Client Comments:

1. Mark BLOOD CULTURE on the order form. Indicate the specific draw site on the form (Line draw, Rt arm, etc).
2. Blood cultures drawn using Mercy lab’s bottles (BacTALERT) should be left at room temperature until the Mercy courier picks up the samples. DO NOT PLACE THE BOTTLES IN ANY INCUBATOR AT YOUR LAB.
3. Send the blood culture bottles at room temperature to Mercy lab.

Comment: 

See beginning of section for ordering help and codes.

Specimen: 

Patients 6 yrs of age and older:  10 ml whole blood drawn into Isolator 10 tube. Short samples decrease the already low number of organisms.

Patients 5 years of age and under:  1.5 ml whole blood drawn into pediatric Isolator tube.

Specimens are to be collected using the following instructions:

• Disinfect the stopper of Isolator tube with 10% PVP iodine.
• Cleanse and disinfect the venipuncture site, and maintain aseptic technique.
• Collect blood sample with the patient's arm in a downward position. (1.5 ml for patient 5 yrs and under) (10 ml for patients over 5 years.)
• Gently invert the tube 8 to 10 times immediately after collection.  Incomplete mixing causes small clots to form.  Clotted samples are unacceptable and must be redrawn.
• Transport promptly to the lab.

RL Client Comments:

• Write in Blood Culture/Fungus on RL order form. Indicate source on order form.
• Send at room temperature.

Performed:

The Sunquest Collection Manager Label automatically prints to the label printer in CVP.  The order comment contains "Venous blood," but is not visible on the label due to the length of the comment.

CVP staff should call lab and make arrangements with lab for collection of specimen in a green no gel tube and handing the specimen off to CVP for testing.

Non-anticoagulated venous blood or peripheral blood from finger or earlobe preferred. Prepare 3 thick and 3 thin smears on separate slides. EDTA blood can be used if slides are prepared within 1 hour of collection.

Prepare slides as follows:
THIN SMEARS:   Prepare at least 3 thin blood smears in the same manner as for a differential.

THICK SMEARS: Place a drop of blood on a slide.  Using the corner of a clean slide or applicator stick, spread the blood in a circle about the size of a dime. If proper thickness is achieved, ordinary print should barely be visible through the wet center.

Allow both thick and thin films to air dry without heating. The thick smear must dry 8-10 hours before staining.
