Blood Test : Blood Cultures

In this test, a sample of blood from a vein is taken (venipuncture). Through special laboratory procedures, the blood is incubated over night. If bacteria are present in the blood specimen, they will grow in the laboratory and be identified.

Using the information derived from the blood culture, it is possible to determine the most appropriate antibiotic for treatment of the patient's infection. Patients who require blood cultures are often admitted to the hospital (pending final culture results, in 24-48 hours).

Here are some instances where blood cultures are performed:

1. Any patient thought to have a blood borne infection (pneumonia, meningitis, and sepsis).

2. Infants under 2 years of age with fever. This age group is at much greater risk for a blood borne infection, particularly in the presence of high fever (sepsis).

3. Elderly patients with an unknown source of fever.

4. Any immunocompromised patient who runs a fever: AIDS patient, diabetic patient, or the cancer patient on chemotherapy.
