What is Single Donor Platelets (SDP)?

It is possible to obtain only Platelets from a Donor by a process called ‘Apheresis’. Like in routine blood donation, 350 ml. of blood is drawn from the donor. This is sent to a special Blood Bag, which is housed inside the Apheresis Machine. The machine spins, separates the Platelets and sends the remaining blood components back to the donor’s body. This cycle is repeated 6 – 8 times and the whole process will take approx 60 to 90 minutes. Almost 300 ml. of Platelets is obtained in this manner from just one donor. The Platelets so collected are called Single Donor Platelets (SDP).
