Transcript text: A patient's blood does not agglutinate when either anti-A or anti-B antiserum is added to it. Name the patient's blood type.
Solution
The answer is the first one: 0 (or O).
Explanation for each option:
0 (or O): This is the correct answer. Blood type O does not have A or B antigens on the surface of the red blood cells, so it does not agglutinate when either anti-A or anti-B antiserum is added.
B: This is incorrect. Blood type B has B antigens on the surface of the red blood cells, so it would agglutinate when anti-B antiserum is added.
$A B$: This is incorrect. Blood type AB has both A and B antigens on the surface of the red blood cells, so it would agglutinate when either anti-A or anti-B antiserum is added.
A: This is incorrect. Blood type A has A antigens on the surface of the red blood cells, so it would agglutinate when anti-A antiserum is added.
Summary:
The patient's blood type is O, as it does not agglutinate with either anti-A or anti-B antiserum.
