Diagnosis and treatment of the etiologic agent of sepsis
When this test is ordered, the reflex tests may be performed and charged.
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%).
Identification of all organisms
Microbial growth is reported.
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.
