Researchers at the University of British Columbia in Canada have found a way to convert type A blood into a universally accepted form, potentially doubling the amount of universally available blood available.
According to Science Magazine, a new study published in Microbiology of nature stipulate that Scientists have discovered a way to change blood type A into a universally accepted type O negative blood type.
Type O negative blood cells are universally accepted because they lack antigens, substances that trigger an immune response.
However, according to the American Red Cross, only 7% of Americans have O type negative blood. Since anyone can receive blood from a person whose blood is O negative, but so few people have it, it is often the subject of high demand and a shortage.
People with blood groups A, B or AB can donate blood only to other people of the same blood type. In addition, blood groups can be negative or positive for antigens that can cause fatal immune system reactions.
The researchers have been able to find bacteria in the human gut that produce two enzymes that cause the antigens to become detached from the blood type A and then transform them into antigen-free type O negative blood cells.
Additional studies must be conducted to ensure that all blood antigens are cleared from type A blood, but if they were effective, type A blood would revolutionize blood transfusions. .
