HOW DO I KNOW MY BLOOD GROUP

Everybody’s blood is made up of the same component that is plasma, red blood cells, white blood cells, and platelet. However, there are different blood types and the type you have depends on the genes your parents passed to you.

You are able to know your blood type is different from another person because of some special protein molecules called antigens and antibodies.

An antigen is any substance that your immune system can respond. The antigens live on the surface of your red blood cells. An antibody is a disease fighting protein in the human body that attacks foreign substances that evade your body.

THE DIFFERENT BLOOD GROUPS

There are four main blood groups as defined by the ABO system that is  – A, B, AB and O.  This grouping is done based on whether or not you have two specific antigens. Each group can either have a positive or negative rhesus.

  • Blood group A has A antigens and B antibodies
  • Secondly, Blood group B has the B antigens and A antibodies
  • Blood group AB has A and B antigens but neither A nor B antibodies.
  • Blood group O doesn’t have A or B antigens but has both A and B antibodies.

THE Rh SYSTEM

The red blood cells have another antigen known as the RhD antigen. If this protein is  present, then your blood group is RhD positive. If it’s absent, your blood group is RhD negative.
This means you can belong to one of these blood groups.

  • An RhD positive (A+)
  • A RhD negative (A-)
  • B RhD positive (B+)
  • B RhD negative (B-)
  • O RhD positive (O+)
