There is normally a tremendous demand for A positive platelets. Platelets are most often used by leukemia patients. They control blood flow in your body and are used to stop bleeding associated with cancer and surgery.
AB Positive Blood Type
A donor with AB positive blood is the universal plasma donor. The Blood Center urges you to consider giving a plasma pheresis donation. Plasma carries clotting factors and nutrients. It is given to trauma patients, organ transplant recipients, newborns and patients with clotting disorders. AB negative donors are the. universal plasma donors. Plasma from AB type blood can be given to all patients needing a plasma transfusion regardless of their blood type. A Plasma pheresis donation is needed most from these donors.
O Negative Blood Type
O negative donors are the universal red blood cell donors. All patients can use o negative blood and it would be most beneficial for everyone if such donors took time to donate whole blood or double red cell apheresis. Red blood cells are used to carry oxygen to all cells. They are given to surgery and trauma patients and those with blood disorders such as anemia and sickle cell anemia.
A Negative Blood
Given the relatively few numbers of donors with the A negative blood type, patients are best served by a platelet pheresis donation.
Donating With B Positive Blood
B positive is a relatively rare blood group, so whole blood donations of this type are very important. B negative is also a relatively rare blood group. Giving whole blood or double red cell apheresis will help the most.
