Question

drag the blood types from the answer bank to identify the blood type that, when added to reagents containing a, b, or rh antibodies, results in the combination shown. answer bank a- ab+ b+ o-

Explanation:

Blood type is determined by the presence or absence of A, B, and Rh antigens. Agglutination (clumping) occurs when antibodies in the reagent bind to corresponding antigens on the red - blood cells. In the first case, there is agglutination only with A - antibody, so it's A - (negative for Rh). In the second case, there is agglutination with B and Rh antibodies, so it's B +.

Answer:

First blank: A -
Second blank: B +
