Blood type is determined by antigens (substances that trigger an immune response) on the surface of red blood cells. There are ABO antigens that designate ABO blood types. This is determined by the ABO gene. for example:
- type A Blood type has A antigen
- type B blood type has B antigen
- type AB Blood type has both A and B antigens
- Type O produce neither A nor B antigens
There are also rhesus monkey (Rh) antigens that determine whether blood is “positive” or “negative.” If there is Rh protein on the surface of your red blood cells, you are Rh positive.If there is no Rh protein on the surface of your red blood cells, your blood is negative.

How can you find out your blood type?
There are three main ways to determine your blood type:
- get a blood test from a doctor
- blood donation
- take a blood test at home
1. Clinical trial
One of the easiest and most effective ways to determine your blood type is to have your blood tested by a doctor. A professional draws blood and runs two tests on the blood sample: forward typing and reverse typing.
During forward typing, a blood sample is mixed with antibodies against type A and B blood. Blood type can be determined by whether or not blood cells stick together when mixed with antibodies. If blood cells stick together when mixed with antibodies against type B blood, it is type B blood.If blood cells stick together when mixed with antibodies against type A blood, it is type A blood.
To check the result, the next step is reverse typing. This means mixing A and B blood cells into a red blood cell-free blood sample (called serum). Type A blood has antibodies to type B blood, and type B blood has antibodies to type A blood. Type O blood contains antibodies against types A and B. Therefore, if adhesion occurs when serum is mixed with type B cells, it is type A blood, and if adhesion occurs when serum is mixed with type A cells, it is your blood type. is type B.
It’s a good idea to call your GP to find out what your out-of-pocket costs for blood typing are and whether your insurance covers them.
