every seven daysHow often can I donate platelets? As long as you are healthy and continue to meet the eligibility criteria, you can safely donate every seven days. Many of our platelet donors schedule regular appointments every other week.
Platelet donors may donate as often as every eight days, and up to 24 times in a 12-month period. Double red cell donors may donate as often as every 168 days.
Apheresis collection of plasma and platelets allows you to donate more frequently than does whole blood donation because the body replaces platelets and plasma more quickly than red cells.
Platelets are blood cells that help stop bleeding. And while a whole-blood donation can be broken into components, one of which is platelets, for patient usage, a unit from apheresis platelet donation can yield approximately six times the number of platelets compared to whole-blood-derived platelet donations.Dec 2, 2015
The antibodies could be harmful if transfused into certain patients. The antibodies are present in plasma — and platelet donations contain a high volume of plasma, so our current efforts are directed at screening blood samples from female platelet donors to test for the HLA antibody.

When considering a platelet transfusion, one must consider the ABO compatibility of the platelets themselves, as well as the accompanying plasma. Platelets, like red blood cells (RBCs), express ABO antigens, although expression is variable and strongly expressed in only 4% to 7% of individuals.Dec 4, 2020
