Blood cultures should be drawn prior to initiation of antimicrobial therapy. If more than one culture is drawn, the specimens should be drawn from different sites. The minimum amount of blood is only to be used in cases where there is a difficult draw. Do not overfill the bottles (>4mL in Pediatric or >10mL in adult aerobic and anaerobic bottles), as this can lead to false positives.
