Your immune system naturally contains protective substances called antibodies. The four blood types (A, B, AB, and O) stem from these genotypes. Six of these combinations (AA, AB, BB, AO, BO, OO) are called genotypes. It’s also possible that two people with type A or type B blood could have a baby with type O blood if they carry the O gene.įor example, parents with AO blood could pass the O antigen to their child, creating OO (or simply O) blood. This means that if you inherit an O from your mother and an A from your father, for example, your blood type would be A. On the other hand, Type O doesn’t contain any antigens and does not affect A and B blood types. You could also get B antigens from both parents, giving you a BB, or a B, blood type. When it comes to blood type, you might inherit an A gene from one parent and a B gene from the other, resulting in the AB blood type. You inherit genes from your parents – one from your mother and one from your father – to create a pair. Type O negative blood is most often used for emergencies.īlood types are determined by genetics. O negative: You can only receive donor blood that is O negative O positive: You can receive donor blood that is O positive or O negative.
If you have blood that is type:Ī positive: You can receive donor blood that is A positive, A negative, O positive, or O negative.Ī negative: You can receive donor blood that is A negative or O negative.ī positive: You can receive donor blood that is B positive, B negative, O positive or O negative.ī negative: You can receive donor blood that is B negative or O negative.ĪB positive: You can receive any blood type – you are a universal recipient.ĪB negative: You can receive donor blood that is AB negative, A negative, B negative or O negative. What blood types are compatible for donation purposes?ĭeciding which type of blood is suitable (compatible) for a person who needs blood depends on the ABO group and Rh group and how they match up. One of the rarest blood types in the world is Rhnull, referred to as 'golden blood'. The list below shows the approximate percentage of donors with each blood type: There are eight main blood types but some are rarer than others. These are the ABO and the Rh-positive/Rh-negative blood group systems. Though there are at least 33 blood group systems, only two are widely used. Your blood also contains antigens, which are proteins and sugars that sit on red blood cells and give blood its type. It also contains white blood cells, which help fight infection and platelets, which help your blood clot.īut that’s not where it ends. The aim is to raise global awareness of the need for safe blood.”Įvery drop of blood contains red blood cells, which carries oxygen throughout the body. I myself being O negative, was always curious to know about all the information related to rare blood groups.ĭr Asha Ojha, said, “World blood donor day takes place on June 14 each year. But those are just the most common categories – what about the rest? What about people with ‘rare’ blood who don’t fit into any of these categories, thanks to uncommon combinations (or absences) of certain antigens? AB negative is the rarest blood group in India.ĭo let us know if you have any questions or comments on this subject.New Delhi: You may already know your blood type: whether it’s A, B, AB or O, and whether it’s positive or negative. The second most prevalent blood group in India is B positive. Therefore we see that the most common blood group in India is O positive. Here is the average blood type distribution in the Indian population: 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.īecause blood type is a trait that is genetically determined - blood types tend to show prevalence in a geographic area. Yesterday we published an article about the world’s rarest blood type. These four blood groups are found in two versions - positive and negative.
