How is claret type determined?

A person's blood type is based on whether or not they have certain molecules or proteins — chosen antigens — on the surface of their crimson claret cells, according to the National Institutes of Health. Two of the main antigens used for blood typing are known every bit "A antigen" and "B antigen." People with type A blood but have A antigens on their ruby-red blood cells and those with type B blood take only B antigens. Individuals with blazon AB claret have both; people with type O claret have neither.

Another protein, the "Rh factor" — also known every bit the "Rhesus" organisation — is also present or absent on crimson blood cells. A person'due south blood blazon is designated as "positive" if they have the Rh poly peptide on their red blood cells, and "negative" if they don't have this protein.

Is claret blazon genetic?

Yes, a person'due south blood blazon is genetic, inherited from his or her parents, according to the Red Cross.

Blood type and transfusions

Claret typing is particularly important for blood transfusions, because certain antigens on claret cells can trigger a person's immune system to assail the donated claret.

People who are Rh-negative can only receive Rh-negative blood, but people who are Rh- positive can receive either Rh-positive or Rh-negative claret, the Reddish Cross says.

What's more, type A blood tin can exist used for transfusions for patients with type A or type AB blood; blazon B claret can be used for patients with type B or type AB claret; and type AB blood can be used for patients with blazon AB blood. Blazon O blood can be used for patients with type A, type B, type AB and blazon O blood.

What blood type is the "universal donor"?

 People with type O blood are chosen "universal donors" considering this type can be used for patients with any blood blazon.

Type O blood is often in curt supply in hospitals, due to need for this universal donor blazon, according to the Red Cross. In particular, blazon O-negative blood is in high demand considering information technology'south the ane most often used for emergencies, when in that location may not be time to determine a patient'southward blood blazon.

What are "rare" claret types?

Although ABO and Rh groups are the near of import blood groups for transfusions, there are hundreds of other antigens that accept been establish on the surface of people's cherry-red claret cells. A person'south claret type is rare if their blood does not accept an antigen that most people have, or if their blood does accept an antigen that almost people lack, co-ordinate to the Cleveland Clinic. Specifically, rare blood types are those that are constitute in one in 1,000 people or fewer.

One of the rarest blood types in the world is known every bit "Rh-null;" fewer than  50 people in the globe have been found to have this blood type, earning it the name "gilt blood," the Cleveland Clinic says.

Tin can blood types change?

A person's claret type does not commonly modify, meaning it stays the same throughout life. Just in some rare cases, claret blazon has been known to modify, including in cases of bone marrow transplants and in people who adult sure types of cancers or infections, according to the Cleveland Clinic.

Blood type and pregnancy

Blood type can be an issue in pregnancy if the mother is Rh negative and the fetus is Rh positive. (The fetus can inherit the Rh factor from either the mother or the begetter.) That'southward because, in this situation, the female parent'southward immune system can react to the fetus' "positive" blood. For this reason, pregnant women have their blood tested to decide claret type. Those with Rh-negative blood tin be treated with a drug called Rh immunoglobulin to prevent a damaging immune reaction if their fetus has a positive blood blazon, co-ordinate to the Cleveland Clinic.

How to observe out your claret type

If you don't know your blood blazon yous can inquire your health care provider if they accept a tape of information technology. If they don't, you may exist able to asking blood typing the adjacent fourth dimension y'all get your blood drawn, according to CNN. You lot can also notice out your blood type if you donate blood, co-ordinate to the Cleveland Dispensary. At that place are also at-home blood tests that can tell you your claret blazon.
