scientists They discovered a new blood group system, solving a 50-year-old mystery. This major development has the potential to save thousands of lives around the world.

For years we have been taught that there are four different blood groups: 0, A, B and AB. Researchers from NHS Blood and Transplant, the University of Bristol and the NHSBT International Blood Group Reference Laboratory 50 years of researchrevealed a new blood group. A new blood group has been found, called MAL. In this way, the origin of the AnWj antigen, which was discovered in 1972 but whose genetic basis was unknown until now, was also clarified.

New NHSBT test to ensure blood group compatibility

Louise Tilley, Senior Researcher at NHSBTstated that this new test will provide better care, especially for patients with rare blood types. Tilley, who has been working on this project for twenty years, indicated that it is difficult to say exactly how many people will benefit from this test.

Although we know blood groups based on ABO and RH factors, there are also different proteins and organic components in blood cells. Therefore, there are different blood group systems. Antigen structures found in the blood are also used to recognize and separate harmful substances. Incompatibility of antigens in blood transfusion Complications may arise that can even lead to death.

NHSBT in Filton International Blood Group Reference Laboratoryhas developed for the first time a test to identify patients with a deficiency of this antigen using genetic testing. This test could be life-saving for patients who may have reactions to blood transfusions rare blood group It can make it easier to find potential blood donors.

Philip Brown, who works in the lab, said he was diagnosed with leukemia about 20 years ago and survived thanks to blood transfusions and a bone marrow transplant. Nicole Thornton, who heads the lab, said unraveling the genetic basis of AnWj is a challenging project. new trial blood group incompatibility will reduce health problems caused by In the treatment of patients with rare blood groups It looks like this will be a significant improvement.
