Aseptic collection technique is the most important factor in preventing contamination of a blood culture. This includes proper skin preparation, use of sterile equipment, and appropriate collection and handling techniques to minimize the risk of introducing outside bacteria into the culture. Collection from multiple sites, size of the needle, and timing of the collection may all be important factors for specific situations, but do not have as significant an impact on preventing contamination as proper aseptic technique.
