Blood Typing

Blood typing is very important when you need blood or are donating blood to another person. It tells you what type of blood you have, either A, B, AB, or O. If you give someone blood you must give them the correct kind depending on what kind you have. To determine your blood they take a small amount and put two chemical drops in with distinct colors. Depending on what drops show up and don't show up tell you your blood type. As I said earlier you can have A, B, AB, or O. That's how blood typing works and why it's important.
