Question

Which of the following blood groups can easily receive blood from people with A positive blood type?
A) A negative
B) B Positive
C) O negative
D) AB positive
E) AB negative

Answer 1

Hint: It is important to note in this system that blood types when transfused to the wrong individual can have a very serious reaction. However, these are not the only methods of blood typing. For organ donation, closer matches are needed.

Complete answer:
The AB system of blood grouping is based on the presence or absence of one or two antigens on the surface of the red blood cells. This combines with the presence of the Rh or Rhesus factor.

Type A blood will have the A antigen on the red blood cells, and the negative sign indicates that it lacks the Rhesus factor. Type A negative can receive blood from A negative, but will have anti Rh antibodies. Answer A is incorrect.

B positive blood contains B antigen and antibodies against A antigen. It will therefore attack the A minus blood that is being given. Option B is not correct.

O negative blood has antibodies against both A and B antigens, and therefore cannot accept A minus blood. Option C is incorrect.

AB positive blood contains both A and B antigens and antibodies against neither, it can accept the A positive blood. Option D is the correct answer.

AB negative contains both antigens and does it have the rhesus factor so it will have anti Rh antibodies and will attack the A positive blood. Option E is not correct.

Hence the correct answer is OPTION(D)

Note: Mothers who are Rh negative may have difficulty if their child is Rh positive as the antibodies in her blood will attack the blood of the developing foetus. The first child may be born, but any other children would be in grave danger.
