Adult patients: No more than 2 or 3 blood cultures should be submitted per 24 hour septic episode with each specimen for culture consisting of 10-20 mL of blood. (20 mL is the recommended volume for adult blood cultures)
Pediatric patients (< 6 years): 1 ml per year of age divided between two blood culture draws. (Example: 3 year old should have two draws with a volume of 1.5 mL per draw)
Neonates to 1 year: 0.5-1.5 ml, single draw.
Although drawing blood cultures before or during the fever spike is optimal for recovery, volume is more important than timing in the detection of agents of septicemia. Proper skin disinfection is critical to reduce culture contamination with normal skin microbiota. Patients on antimicrobial therapy should be drawn when antimicrobial agents are at their lowest concentration.
REDOX 1 (Aerobic) and REDOX 2 (Anaerobic) blood culture bottles are supplied by Metro Lab.
Blood culture bottles should be labeled with patient information, specific draw site (Examples: left arm, red port, PICC line), date and time of collection, total volume of draw and the phlebotomist’s initials.
DO NOT cover bottle barcodes with another label. Blood bottles should be transported to the laboratory at room temperature.
Automatic call-back with positive results (Critical Value)
