![]() ![]() The authors say that more studies are needed to confirm the results and to determine how different blood types or groups may increase the risk of certain diseases, or whether there are alternative explanations for these relationships. And women who were RhD-positive were more likely to experience pregnancy-induced hypertension. New link to kidney stonesĪdditionally, they found a new connection between having blood group B and a lower risk of developing kidney stones. The ABO blood types are defined by carbohydrate moieties displayed on the surface of red blood cells and attached to a protein backbone, known as the H antigen. They also verified that women with blood group O were more likely to experience pregnancy-induced hypertension. The ABO blood types, discovered by Karl Landsteiner in 1901, are medically the most important blood types. Their findings confirmed that people with blood group A were more likely to experience a blood clot and that those with blood group O were more likely to experience a bleeding disorder. The researchers scanned Swedish health registries with information on more than five million people and found 49 diseases that were linked to the ABO system, and one that was linked to the RhD system. Rh factors follow a common pattern of genetic inheritance. While type B was associated with an 11 higher risk, and. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. But those with type AB blood were the most at-risk overall, demonstrating a 23 greater chance of suffering from heart disease than type O. Rh Negative Blood Types: A-, B-, 0- and AB-. article continues after advertisement The researchers hypothesize that the difference between blood types might be. People who are type AB have both A and B antigens on their red blood cells and therefore don’t make any A or B antibodies while people who are type O have no A or B antigens and make. “To help fill this gap, we used an unbiased approach to investigate the link between ABO blood types and RhD groups and more than 1,000 diseases.” Rh Positive Blood Types: A+, B+, 0+ and AB+. “There is still very little information available about whether people with RhD-positive or RhD-negative blood groups may be at risk of certain diseases, or how many more diseases may be affected by blood group,” says first author Torsten Dahlén, a PhD student in the Department of Medicine, Solna, at Karolinska Institutet. ![]()
