This document discusses guidelines and best practices for collecting blood samples for culturing. It emphasizes that strict aseptic technique is essential to avoid contamination. Key recommendations include using trained phlebotomists, sterile single-use equipment, effective antiseptic agents with sufficient contact time on the skin, and obtaining blood cultures from a newly inserted venipuncture rather than an existing intravenous catheter. Adhering closely to protocols can help reduce the high rates of contaminated blood cultures and provide accurate diagnostic information for clinicians.
