Blood is the most precious liquid - Goethe
We all know that most people's blood types are blood type A, AB, and B. Blood type o is also known as all-purpose blood, and the rarest blood type is rh-negative blood.In 2017 in China's Jiangsu province, a woman in labor was examined during a maternity checkup and found that her blood was the The rarest and rarest blood type, China sent this discovery to the international gene pool after comparison, found that the international gene pool also does not have this blood type, this blood type is the only one in the world, so the international gene pool will be included in the record of this blood type.
The father of blood type
Blood, human and animal circulatory system of opaque liquid mostly red, mainly divided into plasma blood cells and platelets. In the 19th century many people were afraid to have a blood transfusion because they couldn't trust their own blood to save another human being's life. And Carl Landsteiner, an Austrian doctor, who was the 1st person to study blood types.
He took blood samples from 20 patients and studied the blood by looking through a microscope. With the help of the microscope, he studied the different blood by grouping the blood types that could mix and those that could not.
After his continuous research, he categorized these bloods into type A and type B. Slowly he discovered that there was a type of blood that could mix with both type A and type B, and he called this blood type O. Later he discovered a 4th blood type that could fuse with both type A and type B. He then called this blood type AB.
After his research, he published the 1st blood type system in human history, thus unveiling the secret of the blood type system. With the advancement of science and medical treatment, blood transfusion has become a common clinical practice, and the blood group system has been widely utilized, and Karl Landsteiner is also known as the "Father of Blood Groups".
We know that there are four common blood types. But when it comes to rare blood types, people probably only think of Rh-negative blood, which is called panda blood and is a very rare blood type. So what are the rare blood types in the world?
A3 blood type
The blood system is categorized into ABO, Rh, and MNS, and there are a few very specific blood types among these blood systems. The following blood types are often referred to as rare blood types, which are not only rare, but also very special. The most common and well known of the rare blood types is Rh-negative blood, also known as panda blood, and this blood is as rare as pandas are around the world.
And the 2nd is p blood type, which is even rarer, in the world this blood type is only likely to be found in 5-8 people out of every 1 million people, and most people haven't heard of this blood type yet.
The third Rhnull blood type is known as "golden blood," which, like its name, is comparable to gold and rarer than panda blood. The owner of this blood type is even rarer, there are only 43 people in the world, and this blood type is more common than type O blood. No matter what kind of rare blood type people have an accident, this blood is able to save their lives. And the 4th rare blood type is the one that the woman in our article has - blood type A3.
Genetically mutated blood type
The woman went to the hospital for a maternity checkup, and the doctor told her to take a blood test to determine her blood type, and then booked the blood in advance to prevent her from hemorrhaging during delivery. However, there was a problem with the results of the test, as the woman's blood was not a common or rare blood type and the results were very vague.
The hospital couldn't find out her blood type for a while, so it had to transfer her blood to a blood screening center. Many researchers were also surprised when her blood appeared at the blood testing center. After all, many of them had never seen such blood with a counter-regularity, and it would be a contribution to the world if her blood was another kind of rare blood.
Even though many blood types have been researched, a patient's life can be in danger because of a blood type mismatch during a transfusion. One more research report is one less life-threatening. So many researchers and scholars from the Blood Screening Center came to conduct research on this special blood.
After the efforts of some researchers in the blood screening center, it was finally concluded that the lady's blood was type A blood. But a blood mixing occurred in her blood. So there was a genetic mutation in her blood, so the hospital could not find out which blood type she had.
Shaw Jianyu, director of the Transfusion Research Office of Jiangsu Blood Center, pointed out that the ABO blood type system usually has A type B type and AB type. And there are many subtypes in each type A, such as A1, A2, A3, if they are subdivided, a *** there are 36 kinds of blood type system.
And this lady's blood type is called A3 blood type, which is not only the rarest blood type in our country, but also the only one in the world. Such a special blood type was researched, and the blood screening center rushed to report to the state, which in turn sent the results of this research to the national gene bank for inclusion. The researchers later explained that this blood type arose because of a mutation in the human genes. There are 342 antigens on red blood cells in this blood type, compared with 160 in most people.
Special features of A3 blood
And one of the special features of this blood type is that this blood is able to be easily accepted by other blood, and other blood types are able to accept this blood type during transfusions. It is very helpful in saving people with blood transfusions, but it is special in that it cannot easily accept other people's blood on its own. That means it can save others, but they may not be able to save her.
But if and when this woman in labor needs blood, she can only use her own blood that she has stored up from her usual blood donations. This woman in labor smiled helplessly as she heard about the special nature of her blood. Her own blood could save other people's lives, but she herself could not easily accept someone else's blood.
I don't know whether to say this lady was lucky or unlucky that her blood was so special that she was able to save thousands of people, but thousands of people were not necessarily able to help her. And if she wants to save herself, she must donate more blood in general. Because this blood type of hers was so rare, she could only go and donate more blood on her own time to store it up so that she could save herself in case of an accident.
There is no harm in donating more blood on a regular basis to a person, and blood donation can prevent and alleviate hyperlipidemia, as well as reduce the incidence of cardiovascular disease. And men who donate blood can reduce the incidence of cancer, can promote the improvement of mental health. It also promotes blood circulation, improves mental health, and increases resistance. You don't have to worry about any unexpected situation when you go to donate blood, because the nurse will select how many milliliters of blood to donate for you according to your physical condition. So going to donate blood from time to time is a favorable and harmless thing for people.
