the method to seperate platelates from blood
Answers
Answer:
HOpe it will help
Explanation:
To separate platelets from a whole blood donation, the blood is kept at room temperature, processed and stored, all within eight hours of your donation. In order to have enough platelets for a transfusion, four to six bags of whole blood from different donors must be pooled together to make one unit of platelets.
Platelets must be used within 5 days of donation. Platelets help stop bleeding in patients undergoing surgery or cancer patients who, due to the side effects of chemotherapy or radiation, need them to prevent hemorrhaging.
Answer
During a platelet donation, called Apheresis, your whole blood is removed into sterile tubing and satellite bags. A machine called a centrifuge spins your blood to separate your red blood cells, platelets and plasma. As the blood is separated, the heavier reds cells sink to the bottom and are given back to you.
