About 328 million people currently live in the U.S. Each year, approximately 6.8 million people in the U.S donate blood. Annually, this adds up to about 13.6 million units of whole blood collected for donation in the U.S. Your blood donations are used for patients in need of surgery, cancer treatment and transfusions for blood loss from traumatic injuries.
Why Cancer Patients Need Blood
For cancer patients, blood transfusions can act as a resource to implement platelets back into the body after heavy treatments such as chemo or radiation therapy. During cancer treatment, blood cells that are made in the bone marrow are often at risk. This lack of blood cell production can cause chronic diseases over time which may affect organs such as the kidneys, spleen and liver.
The Importance of Diversity in the Blood Supply
Maintaining diversity in the blood supply is essential. Some blood types are quite rare and are likeliest to be found among people with shared ancestral origins. Visit our Blood and Diversity page for more information on the need for diversity in the blood supply.
Whole Blood Donation vs. Power Red Donation
As the name implies, “whole blood” donation includes all of the contents within the blood. This includes red blood cells, white blood cells, platelets and plasma. Whole blood donations are typically used to help patients fight cancer, blood disorders and traumatic injuries. The Power Red donation is similar to the whole blood donation, except a phlebotomist uses a special machine to ensure two units of exclusively redblood cells are collected. The machine returns the other blood components to you. Think of it as a more efficient way to yield more fuel for patients. The Red Cross highly encourages donors with O+, O-, A- and B- blood types to try a Power Red donation.
Platelet Donation vs. Plasma Donation
Platelets help your body create clots to stop bleeding. Platelet donations are critical for patients who are fighting cancer, chronic diseases and traumatic injuries. The collection process is unique and a bit different than the whole blood donations, both arms are involved. One arm is used to send blood through the apheresis process using a sterile centrifuge. The centrifuge separates the red blood cells from the platelets. The heavier red cells sink to the bottom during the process. These red blood cells are returned to you through the other arm. It’s important to note that an appointment needs to be scheduled at a specific Red Cross donation center rather than at a mobile blood drive.
Plasma Donation
During a plasma donation, called plasmapheresis, blood is drawn from one arm and sent to the centrifuge that separates out the plasma. The red blood cells and platelets are then returned to you in the same arm. Plasma is used to help patients with severe burns, cancer or other potentially life-threatening conditions. The Red Cross encourages donors with the AB blood type to donate plasma, as this is the universal plasma donor type. One donation provides up to four units of plasma for patients in need. As you can see, blood donation is one of the most important things you can do to help others in need. There is no substitute for blood, and it can’t be manufactured. Every day, blood donors help patients of all ages from all backgrounds.
