That is a correct assumption...

Entusuen's answer is correct but doesn't address the Rh factor of the blood ie the negative (-) or positive (+). Positive means that you have the Rh factor on your red blood cells while negative means that you do not have the factor. You can not give Rh positive blood to a Rh negative person because the Rh negative person's immune system will recognize the Rh factor as "foriegn" and attack red blood cells that have the Rh factor thus destroying the donated RBC's. Therefore the universal donor would be O- not O+. Note however that O+ would be a "universal donor" to all (+) blood types ie AB+ A+ B+ and O+
Also it is important to realize that sometimes other particles are sometimes transfused with RBCs even though great lengths may be taken to remove them. These particles could pose a threat to the recipient or the recipient may mount an immune response toward them

Yes. The red blood cells are based on the presence or absence of antigens. There are two types of antigens: Antigen A and Antigen B. A person can either have both (AB), A, B, neither (O). If a person has both antigens they will have AB blood. If the person contains neither antigens they have O. The blood also contains antibodies: Anti-A, Anti-B, or both. This will "reject" that type of blood. Type A blood carries Antigen A but Anti-B (therefore it does not accept B or AB). Type B blood carries Antigen B and Anti-A (will not accept A or AB). Type AB blood carries Antigen A and B but no Antibodies(can take A, B, AB, O). Type O carries no Antigens, but it carries Anti-A and Anti-B(can only receive O). That is why AB is the universal receiver, and O is the universal donor.

YES AS YOU SAID “O” +ve is universal donor,
AB,+ve is Universal recipient so no problem
Technically you can do transfusions but some times better
Always go for CROSS MATCHING TEST so that
In that test laboratory people will take both the persons blood from
Donor and recipient, then they will test under the microscopic
As long as there is no cross reaction, next moment you can go ahead for
Transfusion, but you must follow the required medical tests for donor,

It is true that AB+ is a universal acceptor while O- is a universal donor not O+.

O positive can donate to all others.
Stay away from one subset of O positive found in California.
When a valley girl gives blood it is called "O, for sure."

Yes this is true, but only for washed, packed red blood cells. This is not true for whole blood, or blood products.

IN PRACTISE IT IS THE BLOOD OF SAME GROUP THAT IS TRANSFUSED AFTER CROSS MATCHING AS THERE CAN BE INCOMPATIBILITY OF MINOR SUB GROUPS.YOUR QUERY IS CORRECT THEORETICALLY TO A LIMITED EXTENT.
