    ​Good morning,

    We use our initial draw (what normally may be discarded) from the central line as the blood culture sample.  This is what our in house microbiologist recommends and we also cite this study below.  It is a small study but has encouraging results.

    ​Hi Erin,
    We use the initial discard for both lumens for our cultures, if it is an initial spike we do both aerobic and anaerobic from the first discard and half the discard for both bottles, and use the subsequent withdraw for other tests.

    Hello all,

    What is the policy in place at your facility for drawing blood cultures? Specifically, are you using initial waste (discard) as part of your blood culture sample or do you use the subsequent draw for the sample?
