What's in your blood?

Even though we only tend to focus on four key blood types, there are actually hundreds of iterations of different proteins and other components that make up our blood. Your type is determined from your genetics, a mix of each parent’s type to create your unique signature. However, there is more to blood than types A, B, AB, and O. Blood contains red blood cells, white blood cells, platelets, and plasma. Each of these components affect how the body reacts to exercise, immunity, diet, and more. Here, you can learn what’s different about each blood type, what healthy blood counts should be, and how you can help donate blood depending on what type you have.
