|CERNER / EPIC MNEMONIC:||C BLOOD|
|TEST INFORMATION:||Used to isolate and identify potentially pathogenic aerobic and/or anaerobic microorganisms causing bacteremia and perform susceptibility testing, when appropriate; establish the diagnosis of endocarditis. Other isolated organisms (i.e. fungi and mycobacteria) may be referred for identification and/or susceptibility testing if medically indicated AND a separate culture procedure has NOT yielded the same organism(s).|
|DAYS PERFORMED:||Daily, 24 hours|
|TURNAROUND TIME:||Preliminary culture reports available after 24 hours or when an isolate is detected. Culture reports of no growth will be issued after 5 days.|
|SPECIAL INSTRUCTIONS:||The specific site of the specimen (i.e. arterial, swan ganz, etc.) MUST be specified on the order or requisition.|
Blood cultures should be obtained prior to the initiation of antimicrobial therapy. COLLECTION OF TWO BLOOD CULTURE SETS IS STRONGLY RECOMMENDED. The specimens should be drawn either at separate intervals, no less than 30 minutes apart, or from two separate sites.

|SPECIMEN REQUIREMENTS:||Blood or bone marrow aspiration|
|REJECTION CRITERIA:||Improperly labeled bottles, expired bottles, refrigerated specimen, insufficient specimen volume, clotted specimen.|
|REFERENCE RANGE:||No growth|
|LIMITATIONS OF TEST:||
|METHODOLOGY:||Automation (continuous monitoring).|
|ADDITIONAL INFORMATION:||It is NOT recommended to culture blood while antimicrobials are present unless verification of an agent`s efficacy is needed. To diagnose endocarditis, 3 sets of cultures may be required. Single blood culture sets are usually inappropriate and are contraindicated except for pediatric patients.|
