So what exactly is a blood type? Well to put it simply it's all based on genetics and your immune system. If someone is type A their body will make red blood cells that have A type markers on the cell surface known as antigens. Inversely their immune system will make antibodies to the markers they don't have. Type A blood will have antibodies to type B markers (antigens) and vice versa.
Take a look at this video to get a better idea of how exactly antigens and antibodies for your blood type works.
The most important thing to remember though is that just one blood donation can save up to three lives. The reason being is that whole blood can be split up into many different parts. You can separate the red blood cells from the plasma and then the plasma can be separated into platelets and clotting factors.
In addition, The American Red Cross estimates that every 2 seconds in the United States a life saving unit of blood is needed. Despite that high number and the projected needs, less than 10% of the U.S population donates blood each year.
Blood donations save lives and it is possible that you or a loved one might need a life-saving transfusion. Staying informed and knowing how you can make big differences in other peoples lives with a resource that is renewable is essential in ensuring that hospitals and physicians have the resources to care for their patients.
Very interesting facts. I have to find out what my blood type is now that I have read your blog.
