what ethnicity has a negative blood type

Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood, in particular, is the universal type needed for emergency transfusions. For example, 51 percent of African-Americans and 57 percent of Hispanics are type O, but only 45 percent of Caucasians are type O. So Sickle cell patients with these blood types must rely on donors with matching blood types within their own community.ĭifferent ethnic and racial groups also have different frequencies of the main blood types in their populations.

For example, U-negative and Duffy-negative blood types are unique to African-Americans. Therefore, it is essential that the donor diversity match the patient diversity. The key factor in the development of Type A can be traced to the struggle for survival long ago, when there was a rapidly dwindling supply of hunting game stock. Certain blood types are unique to specific racial and ethnic groups. Answer (1 of 3): The Type A emerges into the 21st century with many more complex challenges than their ancestors could have imagined. There are more than 600 known antigens besides A and B. If all eligible donors gave at least twice a year, it would help prevent blood shortages. However, shortages of all types of blood occur during the summer and winter holidays. Miller-Keystone Blood Center often runs short of types O and B blood, and AB plasma. TypeĪs you can see, some types mix, while others don’t, but each type is important when it comes to saving lives.

Safe blood transfusions depend on careful blood typing and cross-matching. Each is paired with a + or – Rh factor, which is determined by the presence or absence of substances that can trigger immune responses if they are foreign to the body. The four main ABO blood types are O, A, B, and AB. On the other hand, not all of the ethnic groups share the same proportions of A negative blood types. 53 of Hispanics in the US are believed to have O Positive as their blood type, making them the largest ethnicity with this type of blood. Caucasians are 2x more likely to have a negative Rh factor compared to any other ethnic demographic and 14x more likely to have a negative blood type when compared to people from an Asian ethnicity. This means a few number with approximately 6.6 of the population has A negative blood. Negative Rh factors are the rarest types of blood. Even though all blood consists of the same basic elements, not all blood is alike. The A negative blood type is only present in about 1 out of 16 individuals. Overall, the blood group O had the highest prevalence and AB the lowest percentage among the ethnicities. Over 100 years ago, it was discovered that people have different types of blood. Our study showed ethnicity-related prevalence. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types.
