Medical Assistant Prep / Unit 19 MAS 468 short lesson, about 20 seconds
Let Tubes Fill Completely
Captions available
The idea
Allow each evacuated tube to fill until its vacuum is used up.
In practice
Many tests depend on a set ratio of blood to additive, and clotting tests in the light blue tube require a full draw.
Where people slip
An underfilled tube may be rejected, which means drawing the patient again.
