Blood Typing

There are four general blood types. There’s A, B, AB, and last but not least O. Based on the RH factor each can be either negative or positve. Every person has one blood type and this determines which blood is compatible with your body. This is especially important to doctors who give blood transfusions for if you do not receive the right blood type, it could be fatale. In class we tested for the different blood types based on reactions, visible changes in color, and changes in consitency. After doing this experiment using fake blood samples I wanted to know my blood type useing real blood and so I went to the doctors and they determined that my blood is type B+ . I am glad to know this information for future references!
