People with B blood type can only give blood to people with AB blood type providing that the Rh factor is the same between donator and receiver. (either both positive or both negative Rh)
A person with type A blood can donate blood to a person with type A or type AB.
A and AB
Type A or Type O Negative can give to positive Positive can not give to negative
You can give either A or B blood.
A and AB
yes
No even though Rh factors are same (negatives), O- can't receive A- blood since blood type O has antibodies for type A and B blood which will reject the blood if it is to be injected in.
If your blood type is O negative than you could give it to any person with any blood type.
a person with O+/- blood can only receive O+/- blood respectively. O+ can give blood to any other + blood type, and O- can give blood to anyone.
The AB blood type is known as the universal recipient. Therefore, the groups that a person with this blood type can give blood to are limited. If your blood is AB+, then you can only give to others with AB+ blood. If your blood is AB-, then you can give to people with both AB+ or AB- blood.
One can find out what blood type they have by going and getting their blood tested at a hospital or the doctors. If you give blood they will i've you a card and tell you what your blood type is on the card.
If your ABO blood type is AB, you could potentially give blood to individuals with blood types A, B, AB, and O, as long as there are no other significant blood type incompatibilities. The AB blood type is known as the universal plasma donor because it lacks ABO antibodies in the plasma.
