Finding Ideal Blood Culture Volume in NICU

Finding Ideal Blood Culture Volume in NICU

The investigators want to assess the effectivity of different sample volumes in blood cultures.

The investigators intend to compare yield of 0.5ml sample x2 vs 0.25 ml samples x2 (aerobic and anaerobic media for each volume) taken from the sample taken from the same site and time.

Time to positivity will also be compared, as well as possible contamination rates.

Inclusion Criteria:

• Suspected sepsis

Exclusion Criteria:

• Need for extra puncture in order to withdraw enough blood for the second set of cultures.
• Urgent need for antibiotic without time for cultures.
