If you have ‘’high prevalence’’ your blood is not rare since a lot of people have it on their red blood cells. As we mentioned, human blood has antigens, and some people (160 out of 340) have antigens that are ‘’high prevalence’’. This means that approximately one in sixty-seven donors has a B – blood type. It is one of the rarest blood types in the world.Ī cool B- Blood fact is that it is estimated that only 2% of the world population has this blood type. However, without having a proper network, it can be a race against a clock to get fitting blood (B-) to the patient in crisis. Because few people have B negative blood type, this rare blood is not needed very often. So if you are not sure about your blood type, make sure to check it just in case of an emergency. That is why hospitals must always ensure that the blood types of the donor and those who are receiving the blood are compatible. Still, transfusion is lifesaving only when done properly and on time. It also includes traumas, accidents, and so on. It can be a burn, cancer, lots of different diseases. Millions of people all over the world have benefited from blood transfusion. Since this is a very rare blood type, for people in need, this can mean that getting the right amount of blood on time can be a difficult process and it can involve a serious network of medicine workers, doctors, and other health professionals all over the world. People who have B negative blood type are often called as those who have the most precious blood on the planet. The first one is known as Rh+/Rh- blood group system, while the other one is called ABO. Although science says that there are actually 33 blood group systems, only two of them are commonly used. Antigens cover red blood cells and they help us determine the blood type we have. One of them is known as antigens that are proteins and sugars by their chemical structure. However, we have some additional components in blood. Additionally, our human blood contains platelets that help our blood clot. Red blood cells carry oxygen throughout your body, while white blood cells help us fight infections.
