Because blood type O doesn't have any kind of Antibodies so it can be given to all types of blood.
Blood type AB can only donate to another AB type. Blood type O+ can be given to anyone, but a blood type like A or B or AB can only be donated to a person who has the same exact blood type as the person who is donating their blood.
They can only donate to other AB types, but they can receive blood from A, B, or O.
Type A blood can only be donated to others with Type A blood or AB blood.
If you have blood type a you can donate blood to other people who have type a blood and to people who have type ab blood. People with type a blood are said to have thicker blood than the other blood types.
No, to donate blood safely the donor and the recipient have to have the same blood type.
A, or AB
Bcoz it is rare
A person with Type O can donate to any other blood type, but can only receive blood from another Type O person. A person having blood group O (with absence of Rh-factor) only can donate his blood to any other individual. Rh or Antigen-D is a factor which decides the positivity or negativity of the blood, so the blood group O-negative is considered the universal donor, as it does not effect any of other blood groups.
Blood group A can donate and receive blood from blood group A. Blood group B can donate and receive blood from blood group B. Blood group AB can donate only to blood group AB and receive from any other blood group (they are universal recipent) Blood group O can donate to any other blood group ( they are universal donor) and can receive from only blood group O.
More than just two blood types are not compatible with each other. The four basic types of blood are: A, B, AB, O(not counting Rh). Type A blood can only receive blood from type A and type O. However, type A blood can donate their blood to type A and type AB. Type B blood can only receive blood from type B and type O. However, type B blood can donate their blood to type B and type AB. Type AB blood can receive blood from every type, A, B, AB, and O. However, type AB blood can only donate to other AB. Type O blood can only receive blood from type O. However, type O can donate their blood to A, B, AB, and O. So, AB is the "universal" reciepient and O is the "universal" donor.
Yes. O- can donate to all blood types. O+ can only donate to other positive blood types, including AB+.
You can donate you any blood type, but only accept type O- blood
