![]() As of September 2022, a total of 43 human blood group systems are recognized by the International Society of Blood Transfusion (ISBT). īlood types are inherited and represent contributions from both parents of an individual. Several of these red blood cell surface antigens can stem from one allele (or an alternative version of a gene) and collectively form a blood group system. ![]() Some of these antigens are also present on the surface of other types of cells of various tissues. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. If you are ever concerned about your health, or would like further information on your risk factors for medical conditions and what you can do to lower them (if possible), please make an appointment with your medical professional.Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells.Ī blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). It is always a good idea to go through your family history with your doctor and be well informed on lifestyle choices that can negatively impact your health. Other factors such as lifestyle habits and family history will also play a large part in determining your risk. It’s important to note here that you should never rely on your blood type alone to assess your risk. Both ABs and Bs have a heightened risk of developing ovarian or pancreatic cancers. ABs have a 26% higher risk of gastric cancer and have the greatest risk when it comes to heart disease. Women with type A blood are better protected against falling egg counts.įor ABs and Bs, there is some risk factors you should keep in mind. Women with type O blood can be twice as likely to have a lower egg count and poorer egg quality. There is also a 23% lower risk of heart disease and you are 37% less likely to develop pancreatic cancer.įor the men, if your work means you are exposed to pollution regularly and you are type O you are at a higher risk of obesity. Speaking of the stomach, Os have a lower risk of stomach cancer than other blood types. However, they have a higher vulnerability to stomach ulcers and cholera that is caused by bacteria and viruses. Type Os are less likely to die from malaria. For those with type O there is some good news and some bad news. In terms of risk factors for diseases and other medical conditions, each blood type will have its pros and cons. As the name suggests, these immune defence systems interact with your immune system, which can make you more or less likely to suffer from certain medical conditions. What distinguishes each type is the antigens (that is, the immune defence systems) that are on the surface of the red blood cells. Our blood type is inherited by a mix of our parents’ genes. O negative blood, for example, is universal and can be given to almost anyone. If there is a limited supply, however, there are cases where donors with a different blood type may be able to assist. Usually, medical staff will match donors and patients that have the same type blood. Many of us are already aware of the significance of blood type when it comes to transfusions. The most common blood type here in Australia is O positive and the least common is AB negative. By combining these systems, you reveal your blood type. There is also the Rhesus group that determines if the blood is negative or positive. There is the ABO system where a person may have type A, B, AB or O blood. Studies are revealing that our blood type may have significant effects on our health by heightening or lowering our risks for certain diseases and medical conditions.īlood types can be categorised in two ways. It seems, though, that our blood plays an even bigger role in our health than we first thought. The average person holds around 4.7 to 5.5 litres in their bodies and it is responsible for a number of tasks, from regulating temperature and transporting oxygen to providing tissues with necessary nutrients and playing a key role in our immune system. ![]() You don’t have to be a medical professional to know how important blood is to our health.
