Blood, as you know, is the life fluid. Its flow in our circulatory system makes our life possible. 45% of the blood is made up of the Red Blood Cells (RBC) and 55% is plasma. The most widely used blood categorization system is called the ABO system. It is based on the antigens (proteins) found on the surface of RBCs.
- If antigen A is present on the RBC surface, blood type will be A
- If antigen B is present on the RBC surface, blood type will be B
- In case both these antigens are present, blood type will be AB
- If none of these is antigens is present on the RBC surface, blood type will be O
These four blood groups are found in two versions — positive and negative.
Yesterday we published an article about the world’s rarest blood type. A reader asked us a related question on what are the most commonly found blood groups in the Indian population? Today we will discuss the same.
Because blood type is a trait that is genetically determined — blood types tend to show prevalence in a geographic area.
Most Common Blood Group in India
Here is the average blood type distribution in the Indian population:
- O+ = 32.53%
- O- = 2.03%
- A+ = 21.8%
- A- = 1.36%
- B+ = 32.09%
- B- = 2.01%
- AB+ = 7.70%
- AB- = 0.48%
Therefore we see that the most common blood group in India is O positive. The second most prevalent blood group in India is B positive. AB negative is the rarest blood group in India.
