Description
Why is the Test Done?
• To identify the cause of bloodstream infections, sepsis, or fever of unknown origin
• To guide the use of targeted antibiotics or antifungals
• To detect infective endocarditis, a serious heart infection
• To monitor patients with indwelling catheters, immune suppression, or recent surgeries
• To help evaluate hospital-acquired infections
Test Procedure:
• Two separate venipunctures are performed (commonly from both arms or spaced 30–60 minutes apart)
• Blood is collected into aerobic and anaerobic culture bottles
• No special preparation is needed, but it’s important to collect before starting antibiotics
• The sample is incubated and monitored for microbial growth (usually over 5–7 days)
