Blood Group Types Explained. 1  Your blood group will be A, B, AB, or O. If you have A B or O blood group, you have antibodies in your blood plasma that destroy some of the other blood groups. 2  Your Rh status will be listed as negative (-) or positive (+).
Blood type is categorized based on which antigens are on the red blood cells. There are four antigens, or antigen groups: A, B, AB and O. Each of these can further be divided into positive and negative. For example, a person can have either A- blood or A+ blood. If the cells have a specific type of antigen on top of the main four, called an Rh factor, it is positive.
