Exercise 11: Blood Analysis: Activity 4: Blood Typing Lab Report
1. Red blood cell membranes have agglutinogens that specify that individual's blood type.
2. ABO and Rh antigens
All of these answers are correct.
3. Which of the following statements about blood types is correct?
A person with type O blood has two recessive alleles and has neither the type A nor type B antigen. 4. Antibodies to the A and B antigens are found preformed in the blood plasma.
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.
1. To determine an individual's blood type, drops of the blood sample are mixed separately with antiserum containing antibodies that recognize either type A antigens, type B antigens, or
Rh antigens.
2. Agglutination
All of these answers are correct.
3. Antigens are present on all cells.
4. ABO and Rh agglutinogens cause the most vigorous and potentially fatal transfusion reactions.
1. How did the appearance of the A, B, and Rh samples for the patient with AB- blood type compare with your prediction?
You did not answer this question.
2. Which blood sample contained the rarest blood type?
BLOOD SAMPLE 4
3. Which blood sample contained the universal donor?
BLOOD SAMPLE 4
4. Which blood sample contained the universal recipient?
BLOOD SAMPLE 5
5. Which blood sample did not agglutinate with any of the antibodies tested? Why?
BLOOD SAMPLE 4; THEY HAVE NO ABO SURFACE ANTIGENS, DONT REACT WITH THE ANTI-A OR ANTI-B ANTIGENS.
6. What antibodies would be found in the plasma of blood sample 1?
ANTI-B ANTIBODY
7. 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?
