A blood type test just means checking to see which antigens you do or don't have in your blood. If someone is injured and receives a transfusion from an incompatible type, it means their body will reject it and it will cause more harm than good. So, if you have type a- blood, for instance, you can only receive o- or a- blood.

Does that make sense?
