You can buy a kit on wardsci.com. It is a lot less exspensive to just ask your doctor to do it. When you go to donate blood they will see what type you are then.
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.
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.
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)
yes
A and AB
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.
A person with blood type AB cannot give blood to anyone but can receive blood from anyone
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.
