Which blood sample contained the universal donor?

A universal donor has the blood type O-, which was present in sample 4

When transfusing an individual with blood that is compatible but not the same type, it is important to separate packed cells from the plasma and administer only the packed cells. Why do you think this is done? (Hint: think about what is in plasma versus what is on RBCs.)

It is important to separate the packed cells from the plasma, because the plasma has antibodies within it that could potentially react with the antigens within the recipient on the RBCs. This is also why you only administer the packed cells.

List the blood samples in this activity that represent people who could donate blood to a person with type B blood.

People that could donate blood to a person with B+ blood would be, sample 2 (B+), sample 6 (B-), and sample 4 (O-).

Which blood sample did not agglutinate with any of the antibodies tested? Why?

Sample 4, which had the O- blood type did not agglutinate with the antibodies tested, because, as shown as negative results in each category, none of the antigens were present in the sample.

What antibodies would be found in the plasma of blood sample 1?

The antibodies that would be found in the plasma of sample 1 would be the anti-B antibodies since they weren't detected, meaning the body fought them off. That's why the result was negative.

Which blood sample contained the rarest blood type?

The rarest blood type was found in sample 3, AB-.

Which blood sample contained the universal recipient?

The universal recipient would have a blood type of AB+, which was seen in sample 5.

Why are individuals with the AB blood type known as universal recipients for blood transfusions?

They have both A and B antigens on the surface of their RBCs, and their blood serum does not contain antibodies against A, B, or Rh antigens.
