Medical Assistant Prep / Unit 19 MAS 467 short lesson, about 20 seconds
Inverting Tubes
Captions available
The idea
After filling, tubes with additives are gently inverted to mix the blood with the additive.
In practice
The number of inversions differs by tube and laboratory; one guide says six to eight for all tubes, another eight to ten, another gives counts by tube.
Where people slip
Invert gently, never shake. Follow your laboratory's chart for the count.
