Cell Separator machine used to obtain thrombocytes
What temperature are platelets stored at
room temperature
What is done to prevent platelets from clumping together
They are agitated on a plate
How long do platelets last, and why not longer
7 days, due to risk of bacterial infection
What is required and not required when transiting platelets
