Platelets play a vital role in blood clotting and prevention of excess blood loss. The blood is processed through a cell separator, which retains the platelets and returns the other blood components to the donor’s system. This procedure enables people to donate platelets every month.
Platelet donation is a simple process that takes about an hour and a half to complete.
Plasma donation is a similar process to platelet donation, and takes about 90 minutes. The blood is processed through a cell separating machine that filters out the plasma and returns the red cells and other cellular components to the donor’s system.
Plasma can be donated every 2 weeks where possible.
