Your blood is made from plasma and blood cells. The four main components, plasma, red blood cells, white blood cells, and platelets, work together to keep your body running smoothly. Each part plays a vital role, essential for your overall health.
Plasma is the liquid portion of our blood and is about 90% water. The plasma portion of your blood accounts for more than half of your blood volume.
As your heart beats, the liquid plasma helps carry these blood cells throughout our body’s vast network of blood vessels – veins, arteries and capillaries – allowing them to perform their individual functions.
When you donate whole blood, the red blood cells, platelets and plasma are separated into three different blood products to be used for various patient needs.
Plasma is collected through a process called automation (sometimes referred to as apheresis). This technology enables us to collect plasma and/or plasma and platelets and not the donor’s red blood cells. The process separates the plasma from your other blood components, then safely and comfortably returns your red blood cells and platelets to you.
Red cell donations are also collected using automation. This allows donors to give twice the amount of red cells compared to a whole blood donation.
Platelet donations are also done using automation. The machine collects your whole blood and then separates out your platelets. Your red blood cells, plasma, and some fluids are returned to you.
One automated platelet donation produces one or more complete platelet doses for a patient. It would take six to eight whole blood donors pooled together to produce one complete platelet dose.
Now that your know all about blood, we invite you to come in and share your power and give back to the community. Find a Big Red Bus or OneBlood Donor Center location near you.
