Whole blood donors can donate every 56 days or up to six times a year.
Some people who meet specific minimum height and weight requirements can choose or be advised to make an automated red cell donation. These donors (sometimes referred to as double red cell donors) help save two patients with their single automated red cell donation because it yields enough for two patient transfusions. Automated red cell donors can donate every 112 days or 3 times a year.
People can donate platelets every 3 days or a maximum of 24 times a year. Plasma can be donated every 28 days.
People can donate leukocytes (white cells) every 7 days.
Some people donate various blood components which impacts when they are next eligible to donate. So it's best to check with New York Blood Center to confirm your next accurate donation opportunity.
