If You Belong To the O Blood Group, Here Are 12 Important Things You Need To Know About It


We all know there are different blood types and that’s that. What we don’t realize are the factors that our blood type impact concerning our health. There are many more interesting things to know about your blood group than just a letter. Human blood was first classified into its own four groups by Karl Landsteiner in 1900. Knowing your blood type is of course important for emergencies and in many cases blood matches are important for transfusions and organ transplants. Here is how blood type characteristics can impact your health.

1 This is how blood types are determined?

Blood types are classified into their four groups by the absence or presence of certain factors called antigens within them. Foreign antigens in the body can trigger an immune response. Stimulated by the antigens, the transfused blood is attacked by the host’s immune system. This is one of the biggest reasons you always need to know your blood type so that there is a safe match during a required transfusion.

2Type O blood characteristics

The four main blood types as mentioned before are determined by the absence or presence of A and B antigens in the surface of the red blood cell and the antibodies of the A and B in plasma. Within blood, there is also a protein present called the Rh factor; this too can be absent or present in the blood.

3There are no antigens present in O blood groups

The Rh factor and the absence of presence of antigens collectively determine the blood grouping which is 8 types and these are A+, A-, B+, B-, O+, O-, AB+ and AB-. The unique thing about type O blood is that there are neither A or B antigens present in the red blood cells but they do have A and B antibodies present in the blood plasma.
