The ABO-RH blood type printing system is an extremely successful method that helps medical professionals safely perform blood transfusions around the world.

The French Blood Foundation (EFS) scientists have successfully identified extremely rare 48Th A blood type group called “Gwada negative”, originated in a blood sample initially drawn about 15 years ago.

Although it is important for doctors to know about these blood types so that patients can get the best care as possible.
Many people are familiar with four wide human blood types – A, B, AB and O – and are likely to know that they are also positive or negative varieties (what is called Rh factor). However, this is actually only the tip of the iceberg when it comes to the complexity of human blood types. Actually people have theoretically Millions different types of blood because more than 600 antigens were found in human blood cells. Any combination of those antigens could be considered a new type of blood.
However, the International Blood Transfusion Society (ISBT) recognizes only 47 different blood type groups, and the latest was added last year after a 50 -year secret. Now, according to a press release about LinkedIn, published by the French Blood Institution (EFS), 48, 48Th The member officially joined the party. About 15 years ago, researchers received blood from a French woman from the Caribbean island in Guadelup, speaking like a Gwada. Before surgery, the patient performed blood by performing normal tests.
An unusual antibody associated with this blood was found in 2011, but only in 2019. Determining the DNA sequence found that the genetic mutation is responsible for the unique blood type, which was officially acknowledged this month by ISBT. After the patient’s homeland, researchers called the Gwada negative and confirmed that the woman inherited the type of blood from her parents, who each had a mutated gene.
‘[This] Undoubtedly, the only known case in the world, ”said EFS Medical Biologist Thierry Peyrd, Agency France-Press (AFP) .- It is the only personality in the world compatible with herself.”
It is extremely important to know the blood structure of the antigen before blood transfusion, as a discrepancy can lead to a life -threatening immune response. Basically, your body thinks that antigens attached to foreign blood cells are intruders. Although there are potentially millions of blood types, blood transfusions that correspond to your type according to the established ABO-RH type system have 99.8 percent. The likelihood of success. That is because Some Differences, transfusion will probably be successful.
However, it is still important to determine these types of extremely rare blood to prevent life -threatening immune responses. “The discovery of new blood groups means that in patients with rare blood, to offer a better level of care,” the EFS team said in a press release.
Although the current number of blood groups is 48 years old, it will probably not be the last number. The achievements of the gene sequence have overflowed the discovery of these blood groups. For example, 44Th A member of this group, known as ER, has been discovered in 2022, which means that scientists are currently discovering more than one new blood group per year.
2025 May have another or two blood surprises.
