Question

For each blood type, select the expected positive agglutination results from mixing the blood with each of the antibodies.

a) A
b) B
c) AB
d) O

Answer 1

For determining blood type, agglutination with anti-A or anti-B antibodies indicates the presence of respective antigens on red blood cells. Type A agglutinates with anti-A, Type B with anti-B, Type AB with both, and Type O with neither. Blood type AB/Rh- will have Rh antibodies.

Step-by-step explanation:

The process of determining your blood type involves mixing your blood with antibodies against type A and B blood. The presence of these antigens on your red blood cells determines your blood type. Let's go through the expected agglutination results for each blood type when mixed with these antibodies:

• Type A: Agglutination occurs with anti-A antibodies, but not with anti-B antibodies.
• Type B: Agglutination occurs with anti-B antibodies, but not with anti-A antibodies.
• Type AB: Agglutination occurs with both anti-A and anti-B antibodies, as type AB blood has both A and B antigens.
• Type O: Agglutination does not occur with either anti-A or anti-B antibodies, as type O blood has neither A nor B antigens.

For question 10, if a person has blood type AB/Rh-, they will have Rh antibodies because they lack Rh antigens. They will not have anti-A or anti-B antibodies since their blood contains both A and B antigens.
