Thereof, what is the order of draw for blood culture?
The draw order for specimen tubes is as follows: Blood culture. Blue tube for coagulation (Sodium Citrate) Red No Gel. Gold SST (Plain tube w/gel and clot activator additive)
Also, why do you draw blood cultures from 2 different sites? Usually, two blood samples are collected from different veins to increase the likelihood of detecting bacteria or fungi if they are present in the blood. A second set of blood cultures should be collected from a different site, immediately after the first venipuncture.
Moreover, when Should blood cultures be drawn?
Most guidelines state that blood specimens should be collected in the absence of antimicrobials, at or around the time of fever spikes, and a 30–60 min interval between samples has been arbitrarily recommended (Weinstein, 1996).
Why is aerobic blood culture first?
The aerobic bottle should be inoculated first for several reasons, including the fact that air from the tubing is pulled into the bottle compromising an anaerobic environment and if flow of blood is interrupted, most of the organisms that cause septicemia (aerobic) will be recovered.
