|Blood Culture ([LAB000185])
C BLDN - Blood Culture Screen
Collection of 8-10 mL of blood is optimal for Aerobic and Anaerobic bottles. 1-3 mL of blood is optimal for a Peds bottle.
Culture for aerobic and anaerobic bacteria and yeast; organism identification and antimicrobial susceptibility, if appropriate.
After locating a vein, cleanse the venipuncture site thoroughly with 70% isopropyl alcohol. Use a ChloraPrep One-Step to concentrically swab outwardly beginning at the collection site. Allow the site to dry and DO NOT RE-PALPATE. Mark the BACTEC bottles to the desired fill level by locating the hatch marks on the side of each bottle. Mark the initial volume of the fluid contained in the bottle and then count two (2) hatch marks above the initial vollume and mark again. Each hatch mark indicates 5 mL. Remove flip-off cap(s) from bottle(s), wipe with alcohol pad and allow to dry. Use a butterfly or syringe to collect 8-10 mL of blood into each bottle, beginning with the aerobic bottle (gray label/blue ring top) first, followed by 8-10 mL into the anaerobic bottle (purple label/purple ring top). For pediatric or difficult-to-draw patients, collect 1-3 mL into a Peds Plus bottle (pink label/silver top). Wipe tops of bottles with alcohol prep after collection is complete. Collect two sets of cultures per febrile episode from separate collection sites, or wait a minimum of 15 minutes if using the same collection site.
DO NOT COVER BARCODE ON BOTTLE WITH PATIENT LABEL. Place patient label perpendicular to the bottom of the bottle.
Check bottles for expiration date before using. Do NOT cover barcode on bottle with patient label. Prior to use, inspect each bottle for evidence of contamination, damage, or deterioration. Store BACTEC bottles in a cool, dry place - out of direct sunlight.
For Aerobic and Anaerobic bottles, a minimum of 3 mL in each bottle should be collected. For a Peds bottle, a minimum of 0.5 mL should be collected.
Room temperature. Do not refrigerate. Do not put blood culture bottles in pneumatic tube system.
After cleaning bottle top(s) with alcohol swab, inject 8-10 mL of blood into each Aerobic and Anaerobic blood culture bottles. Inject 3 mL into Peds bottle.
Transport to laboratory as soon as possible.
|Causes for Rejection:
Refrigerated bottles, submission of vials other than BACTEC bottles, unlabeled or improperly labeled bottles, no date and time of collection on specimen or missing collector information on order. Blood cultures are included on the Specimen Exception List.
Negative cultures are held 5 days.
BACTEC FX - continuous monitoring instrument. Positive bottles are sub-cultured and organisms identified using laboratory protocol. Susceptibilties are performed, if appropriate.
Culture, blood; Bacterial blood culture; Brucella blood culture; septicemia; bacteremia
Suspected bloodstream infection with aerobic, anaerobic bacteria, or yeast
|Patient Preparation :
Follow directions using blood culture cleansing kit for cleansing of the venipuncture site. Inadequate cleansing may result in contamination or false positive cultures.
|CPT 4 Code:
87040, additional if indicated
Positive culture results are considered a critical value and notification will be performed upon recognition of positive result.
DO NOT COVER BAR CODE LABEL ON BOTTLE WITH PATIENT LABEL. Place patient label perpendicular to bottom of bottle.
Optimal blood volume for culture is 8-10 mL (1-3 mL for Peds bottle). A suboptimal volume of blood can adversely affect recovery and/or time of detection of organisms. Interpret results accordingly.
|When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent.
