What happens if someone with a different blood type gives you blood?

Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be life-threatening.

Why can a patient with type O blood get blood only with the same blood type donors?

But if you have type O blood, your red blood cells have neither A or B markers. So: Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood. A person with O blood can only get a transfusion with O blood.

What blood type Cannot mix?

The blood types must be compatible to avoid an ABO incompatibility reaction. For example: People with type A blood will react against type B or type AB blood. People with type B blood will react against type A or type AB blood.

Why can type O blood donate to everyone?

People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group.

What would happen if you were given a blood type other than yours?

Medically speaking, what would happen if a person were to be given a blood transfusion using a blood type other than their own? That depends on what type of blood was given and the recipient’s blood type. There are three major antigens (things on outside of blood cells that cause allergic reactions). The antigens are A, B, & O.

Is it safe to donate blood to people with different blood types?

In the U.S., about 40\% of Caucasians, 31\% of Hispanics, 27.5\% of Asians and 26\% of African Americans carry this blood type, which is safe to donate blood to others with type A blood, as well as those who are type AB. In addition, people with type A may also receive transfusions of type O blood.

Why is AB blood type considered a universal recipient?

For this reason, those with AB blood type are sometimes referred to as universal recipients because they can accept blood from anyone; however, because of the presence of both antigens on type AB red blood cells, people with AB blood can only donate it to others with the same type.

Does it matter if you have AB or O blood type?

If a person with AB gets anything different, it does not matter. If a person with O gets anything different, that’s likely a huge problem called a major hemolytic transfusion reaction.
