Question

What is the condition for B antigen mismatch?

1) Only B antigen mismatch
2) Only zero antigen mismatch
3) Both B antigen mismatch and zero antigen mismatch
4) Neither B antigen mismatch nor zero antigen mismatch

Answer 1

A B antigen mismatch occurs when the recipient has blood type B and the donor has blood type A or AB, while a zero antigen mismatch occurs when the recipient has blood type O and the donor has blood type A, B, or AB.

Step-by-step explanation:

The condition for B antigen mismatch is option 3) Both B antigen mismatch and zero antigen mismatch.

In the ABO blood typing system, individuals can have type A, B, AB, or O blood depending on the presence or absence of A and B antigens on red blood cells. If there is a mismatch between the blood types of the donor and recipient, it can lead to complications during blood transfusion.

A B antigen mismatch occurs when the recipient has blood type B and the donor has blood type A or AB. This is because the recipient's immune system can produce antibodies against the A antigen on the donor's red blood cells, causing clumping or agglutination.

A zero antigen mismatch occurs when the recipient has blood type O and the donor has blood type A, B, or AB. This is because the recipient's immune system can produce antibodies against both the A and B antigens on the donor's red blood cells.
