How is the blood type determined?
person’s blood type According to it, it is based on the presence of specific molecules or proteins (called antigens) on the surface of red blood cells. National Institute of Health.. Two of the main antigens used for blood typing are known as “A antigen” and “B antigen”. People who have type A blood have only A antigen in their red blood cells, and people who have type B blood have only B antigen. Individuals with ABO blood have both. People with O-type blood do not have either.
Another protein, “Rh factorAlso called the “rhesus” system, it is also present or absent in red blood cells. If the red blood cells contain the Rh protein, the blood type is designated as “positive”, otherwise it is designated as “negative”. This protein is missing.
Is your blood type genetic?
Yes, according to the Red Cross, a person’s blood type is hereditary and inherited from their parents.
Blood type and blood transfusion
Blood type is especially important transfusionThis is because certain antigens on blood cells can provoke the human immune system to attack donated blood.
According to the Red Cross, Rh-negative people can only receive Rh-negative blood, while Rh-positive people can receive Rh-positive or Rh-negative blood.
Besides, Type A blood It can be used to transfuse patients with type A or AB blood. Type B blood can be used for patients with type B or type AB blood. ABO blood can be used for patients with ABO blood. Type O blood can be used for patients with Type A, Type B, Type AB, and Type O blood.
What kind of blood type is a “universal donor”?
People with ABO blood group are called “universal donors” because this type can be used for patients of all blood types.
According to the Red Cross, ABO blood donations are often deficient in hospitals due to this universal donor-type demand. In particular, type O negative blood is in high demand because it is most often used in emergencies where you may not have time to determine the patient’s blood type.
What is a “rare” blood type?
ABO and Rh blood groups are the most important blood types for blood transfusions, but hundreds of other antigens have been found on the surface of people’s red blood cells. According to the report, a person’s blood type is rare if the antigens that most people have are not in the blood, or if the antigens that most people do not have are in the blood. Cleveland Clinic.. Specifically, rare blood types are found in less than 1 in 1,000 people.
One of the rarest blood types in the world is known as “Rh-null”. According to the Cleveland Clinic, less than 50 people in the world have this blood type and are named “golden blood.”
Does the blood type change?
A person’s blood type usually does not change. That is, it remains the same throughout life. However, according to the Cleveland Clinic, blood types are known to change in rare cases, such as in the case of bone marrow transplants or in people who have developed certain types of cancer or infections.
Blood type and pregnancy
Blood type can be a problem with pregnancy If the mother is Rh negative and the foetation is Rh positive. (The foetation can inherit Rh factor from either the mother or the father.) This is because the mother’s immune system can react to the fetal “positive” blood in this situation. For this reason, pregnant women undergo a blood test to determine their blood type. According to the Cleveland Clinic, people with a Rh-negative blood group can be treated with a drug called Rh immunoglobulin to prevent impairing the immune response if the fetal blood group is positive.
How to find your blood type
If you don’t know your blood type, you can ask your healthcare provider if you have a record of it. If this is not the case, you may be able to request a blood group test the next time you take a blood sample. CNN.. According to the Cleveland Clinic, you can also know your blood type by donating blood. There is also a blood test at home that will give you an idea of your blood type.
