Why should we know our blood group? Anyone who has watched medical dramas on TV is aware that there are 4 basic blood groups – A, B, AB, and O. They are also aware of the need to match blood type when giving a blood transfusion. The basic types indicate the presence or absence of antigens and antibodies in your blood. Your blood type is also about your Rhesus factor which makes your blood type negative or positive. So if you are Rh positive and A type blood, your blood type is A+
Medical Emergencies – Hospitals will always run a test to check your type but it’s always good to know. Some blood types are rarer than others. People with type O-negative are universal blood donors, meaning they can give blood to any blood type. Whether you’re O-negative or another blood type, the UK badly needs more blood donors. Also, having a blood test done is the first step to becoming a bone marrow donor, which could save someone’s life as well.
