Question

You know that A and Rh antigens are present and B antigens are not present. With this information, what is our patient's blood type?

Answer 1

If A antigens are present, then the blood type is A or AB.

If B antigens are not present, then the blood type cannot have B, so it's not AB. It's only A.

If Rh antigens are present, then the blood type is positive.

Therefore, the correct answer is A+.
