Seven Things You Didn't Know About Platelets

Lauren Frame January 17, 2020

1. Just like your red blood cells and most of your white blood cells, your platelets are produced in your bone marrow. 

2. Platelets are small, disk-shaped cell fragments that don’t have a nucleus. They help your body form clots and stop bleeding. These tiny cells travel to the site of an injury, sticking to the blood vessel walls to essentially plug up the injury and helping stop bleeding.

3. Bone marrow is the spongy tissue in the cavities of your bones that manufactures stem cells. These stem cells then develop into platelets, red blood cells and white blood cells.

4. Each day, the average healthy adult produces about 100 billion platelets. That equals out to 1 million platelets produced every second.

5. Platelets only live about seven to 10 days in your body. That means when you donate platelets, your donation must be transfused within five days.

6. One automated platelet donation produces one or more complete platelet doses for a patient. It would take four to six whole blood donors pooled together to produce one complete platelet dose.

7. When you give platelets, your body immediately begins converting more stem cells into platelets and will replace the donated platelets within 72 hours. You can learn more about the platelet donation process on our website.

What happens when your bone marrow is unable to produce enough platelets?
Owen was diagnosed with Chronic Granulomatous Disease when he was just 12 weeks old. The condition severely compromised his immune system, putting him in danger.

To cure his disease, Owen needed a bone marrow transplant.

When he was just 1 year old, Owen was fortunate enough to find a perfectly matched bone marrow donor. He relied on blood and platelet donors to keep him alive while he waited for his transplant to take and allow his body to begin generating the healthy new stem cells, blood cells and platelets needed to keep him alive.
