Here’s how your blood is collected depending on the type of donation — and how often you can return to generously donate again.
A pint of whole blood is drawn and is processed in a laboratory to be separated into components (red blood cells, plasma, and sometimes platelets and cryoprecipitate). It takes just 20 minutes of your time and it can save up to four lives. You can donate every 56 days.
An apheresis blood donation is the process of blood drawn through a special machine to separate it during the donation, so that only certain parts of the blood are collected and the remainder is returned to you.
Double Red Cell
Double red cell donations are performed using an apheresis machine. The donation takes about 35 minutes and allows you to donate two pints of red cells. We do not collect your plasma or platelets. You can donate every 112 days.
Plasma is the liquid portion of your blood that transports water and nutrients to your body's tissues. We do not collect your red cells. Sometimes we can collect your plasma and platelets at the same time. You can donate every 28 days.
Platelets are the very small cell fragments in your blood that help stop bleeding. Cancer patients receive a lot of platelets due to the effects of chemotherapy. You can donate platelets every 7 days and can give up to 24 times a year. Appointments are recommended for platelet donations.
