There are two donation types:
- Whole blood donation
- Platelet donations: Platelets are vital to your body's ability to clot and are used to help treat many diseases. Platelets are collected using a sterile, single-use needle and a disposable apheresis kit. Blood is drawn into an apheresis machine that separates into components. The platelets are collected in a separate bag with plasma and the blood is returned to you. This process is repeated until the amount of platelets needed have been collected. The collection process takes 45 minutes to two hours. During this time, you may read or watch TV. We may also collect plasma and/or red blood cells depending on your blood counts.
There are several special donation programs that we offer:
- Transfusion Buddy Program: Children who are transfused chronically, such as sickle cell disease patients, tend to develop antibodies. The Transfusion Buddy Program provides patients with blood from donors whose red cell antigens closely match their own. This may reduce the amount of antibodies the patients form, and make finding compatible blood for their future transfusions easier. Please contact the Blood Donor Center if you are interested in becoming a Transfusion Buddy.
- Directed donations: When families want to recruit specific donors for their child, a directed donation can be made. The child’s physician or the Blood Donor Center can provide the family with more information on this process. Access the directed donations factsheet in English and Spanish for more information.
- Autologous donations: Prior to surgery, some children can give blood to themselves; this is called an autologous blood donation. The child must be healthy, at least 12 years old, weigh more than 75 pounds and cannot be anemic. Access the autologous donations factsheet in English and Spanish for more information.
The most common reason to receive a transfusion is to replace blood or one of its parts that are lost from surgery, trauma or burns. Premature infants often receive blood transfusions to replace blood taken for laboratory tests and/or because their system isn't producing enough blood on its own. Children with diseases such as leukemia, kidney disease and sickle cell anemia also may require blood transfusions.
