Blood Cultures Come First
Captions available
The idea
When blood cultures are ordered with other tests, the culture bottles are always filled first.
In practice
Drawing cultures first reduces the chance of contaminating them with additives or with organisms from other tubes.
Where people slip
Follow the laboratory's specific disinfection and collection steps for cultures, which can be stricter than for routine tubes.
