Question

multiple choice question
type ab blood exhibits agglutination in which antisera?

○ anti - a and anti - b

○ anti - b only

○ anti - a only

○ neither anti - a nor anti b

Explanation:

Type AB blood has both A and B antigens on its red blood cells. Agglutination occurs when the corresponding antibody (antiserum) reacts with the antigen. Anti - A antiserum reacts with A antigens, and Anti - B antiserum reacts with B antigens. Since AB blood has both A and B antigens, it will agglutinate in both Anti - A and Anti - B antisera.

Answer:

Anti - A and Anti - B
