If person with O blood group receives blood of person with AB blood group it can cause rhesus factor but not other way round

Negative and Positive blood types refer to the presence of the Rhesus D (RhD) antigen. Rhesus is the second main blood group typing after the A,B,O system.

e.g.

AB+ means the blood cells have A and B and RhD antigens present on the blood cell surface.

O- means that A and B and RhD antigens are not present on the surface of the blood cell.

The classic blood typing into groups A, B, AB or O is only one way to divide up the population. Also whether you are rhesus negative or positive can play a big part. If you are type O but rhesus positive, your blood cannot be given to someone type O but rhesus negative or their immune system will react to the rhesus part of the donated blood.

antigen D is the most important
