Collecting blood cultures with multiple skin sites and both aerobic and anaerobic bottles at each site maximizes the chance of recovering any pathogen and helps tell true infection from contamination. The aerobic bottle supports growth of organisms that need oxygen, while the anaerobic bottle favors those that grow without it, so using both types at a site covers a broader range of potential pathogens. Sampling from two separate sites reduces the risk that a transient bacteremia is missed or that a contaminant from the skin is mistaken for a true infection, since a genuine pathogen is more likely to appear in more than one specimen. For pediatric patients, total blood volume is limited, so a smaller-volume approach is used—one bottle from each site—while still attempting to sample from two sites to preserve diagnostic yield. Always pair collection with proper antiseptic technique and aim to obtain samples before antibiotics when possible.
