Out of the majority, here is a list of numerous blood bank which provide 24-hour blood bank services:ДЎ.

In some cases, a person with Rh-negative blood can carry a child with Rh-positive blood, resulting in a dangerous condition called Rh incompatibility. When it comes to the Rh factor, people with Rh-positive blood can receive either Rh-positive or Rh-negative blood, while people with Rh-negative blood can receive only Rh-negative blood. However, people with type O blood can receive only type O blood. This is why people with type O blood are considered 'universal donors'. Everyone can receive type O blood because it doesnвЂ™t contain any antigens. For example, AB blood has both the A and B antigens, so a person with this type of blood can receive either type A or B blood. Keep in mind that blood types donвЂ™t always need to be an exact match to be compatible. This can have life-threatening results, which is why medical centers worldwide have strict procedures to keep this from happening.

For example, if you have type B blood mixed with type A blood during a transfusion, your antibodies will destroy the A antigens. However, antibodies can also attack antigens that arenвЂ™t in your natural blood type. Usually, they defend against viruses and bacteria. 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. ItвЂ™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.ДЇor 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 doesnвЂ™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 вЂ“ one from your mother and one from your father вЂ“ to create a pair. Type O negative blood is most often used for emergencies.Д«lood 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:ДЄ positive: You can receive donor blood that is A positive, A negative, O positive, or O negative.ДЄ negative: You can receive donor blood that is A negative or O negative.Д« positive: You can receive donor blood that is B positive, B negative, O positive or O negative.Д« negative: You can receive donor blood that is B negative or O negative.ДЄB positive: You can receive any blood type вЂ“ you are a universal recipient.ДЄB 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?Дeciding 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 infectionВ and platelets, which help your blood clot.Д«ut thatвЂ™s not where it ends. The aim is to raise global awareness of the need for safe blood.вЂќД®very 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.Дr Asha Ojha, said, вЂњWorld blood donor day takes place on June 14 each year. But those are just the most common categories вЂ“ what about the rest? What about people with вЂrareвЂ™ blood who donвЂ™t fit into any of these categories, thanks to uncommon combinations (or absences) of certain antigens? New Delhi: You may already know your blood type: whether itвЂ™s A, B, AB or O, and whether itвЂ™s positive or negative.
