Testing Algorithm
When this test is ordered, the reflex tests may be performed and charged.
Method Name
Automated or Manual Detection of Positive Blood Cultures with Conventional Identification Methods
Reporting Name
Bacterial Culture, BloodSpecimen Type
Whole Blood CultureThis test is available by special request only-preapproval by testing lab is required.
Collection Instructions: Incubate blood bottles at 35° C for 24 hours before sending.
Additional Information:
1. It is strongly recommend that blood bottles are incubated at client location on an automated instrument until they flag positive and Gram stain confirms growth is present. The bottles can then be submitted under test IDENT / Organism Referred for Identification, Aerobic Bacteria.
2. Include a completed microbiology request form.
Forms: If not ordering electronically, complete, print, and send a Neurology Test Request Form-General (T732) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/neurology-request-form.pdf)
Specimen Minimum Volume
10-20 mL for adults; 1-3 mL for pediatric patients

Clinical Information
Bacteremia results when bacteria multiply at a rate that exceeds removal by phagocytes. The clinical pattern of bacteremia may be transient, intermittent, or continuous. Transient bacteremia often occurs after manipulative procedures (dental procedures, cystoscopy) or surgery in contaminated areas of the body. Undrained abscesses (intraabdominal, pelvic, hepatic) may result in intermittent bacteremia. A hallmark feature of subacute bacterial endocarditis is a continuous bacteremia.
The sources of bacteremia are genitourinary tract (25%), respiratory tract (20%), abscesses (10%), surgical wounds (5%), biliary tract (5%), other known sites (10%), and unknown sites (25%).
Reference Values
No growth
Identification of all organisms
Cautions
As a general guideline, 2 sets of cultures should be collected per febrile episode in adult patients, no more than 4 blood culture sets should be collected in a 24-hour period, and blood cultures should be collected prior to administration of antibiotics.
