Blood Typing Lab

If the patient's blood type is AB , what would be the appearance of the A, B, and Rh samples?

A, clumped; B, clumped; Rh, unclumped.

Which blood sample contained the universal recipient?

AB+

Which blood sample contained the rarest blood type?

AB-

cause the most vigorous and fatal transfusion reactions

ABO and Rh antigens

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

B+, B-, and O-

which of the following statements about blood types is correct? A) A person with type A blood can have two alleles for the A antigen or one allele for the type A antigen and one allele for type B antigen B) a person with type B blood must have two alleles for the B antigen C) a person with type AB blood has two alleles for the A antigen and one allele for the B antigen D) a person with type O blood has two recessive alleles and has neither the type A nor type B antigen

D

How did the appearance of the A, B, and Rh samples for the patient with AB- blood type compare with your prediction?

My prediction matched the results because A was clumped, B was clumped but Rh was not (it was smooth).

Which blood sample contained the universal donor?

O-

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

Sample 4 did not agglutinate with any of the antibodies tested. This is because none of the antigens were present. It was type O

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.)

The plasma contains the antibodies that could react with the recipients antigens on RBCs

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.

agglutination reaction indicates the presence of what?

agglutinogen

antigens on red blood cell membrane that determine a person's blood type

agglutinogens

Agglutination A) results in a potentially life-threatening blood transfusion reaction B) results in red blood cell lysis C) indicates the presence of an agglutinogen D) all of these answers are correct

all correct

ABO and Rh antigens A) can cause incompatible blood types B) present in the blood of a donor can react with antibodies in the blood of a transfusion recipient, resulting in clumping C) cause the most vigorous and potentially fatal transfusion reactions D) all of these answers are correct

all of these antigens are correct

What antibodies would be found in the plasma of blood sample 1? It is A+

anti-B antibodies

antigens A) cause anemia B) are present on all cells C) are specific to red blood cells D) are genetically determined lipoproteins

are present on all cells

Antibodies to the A and B antigens are

fond preformed in the blood plasma

a person with Type AB blood can have what genetic makeup?

one allele for Type A antigen and one allele for type B antigen

To determine an individual's blood type, drops of the blood sample are mixed A) separately with antiserum containing antibodies that recognize either type A antigens, type B antigens, or Rh antigens B)with serum from the patient to observe whether they have antibodies to the A, B, or Rh agglutinogens C) with antiserum containing antibodies that recognize both A and B antigens D) with lard or butter

separately with antiserum containing antibodies that recognize either type A antigens, type B antigens, or Rh antigens.

what happens if a blood transfusion recipient has antibodies(agglutinins) that react with antigens present on the transfused cells?

the red blood cells will become clumped together, or agglutinated, and then lysed, resulting in potentially life threatening blood transfusion reaction

a person with Type A blood can have what genetic makeup?

two alleles for the type A antigen or one allele for the type A antigen and one for the absence of either the type A or type B antigen

a person with Type B blood can have what genetic makeup?

two alleles for the type B antigen or one allele for the type B antigen and one for the absence of either the type A or type B antigen

a person with Type O blood can have what genetic makeup?

two recessive alleles and has neither type A nor type B antigen
