What type of is 1st in your order of draw?
Blood culture (sterile tube)
What is the tube top color for a blood culture?
Can vary depending on brand and manufacturer but it is noted as “Blue and Red bottle, yellow SPS”
When drawing a blood culture which bottle should be drawn first and why does it matter?
Depends on method BUT if you are using a method where there is air introduced BEFORE the bottle then you must use the aerobic bottle first. Introducing oxygen into the oxygen poor environment of the Anaerobic bottle can ruin test results.
