Physioex Lab: Blood Typing

Which blood sample contained the rarest blood type?

Sample 3

Which blood sample contained the universal donor?

Sample 4

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

Sample 4, O- is the blood type that is known as the universal donor because it does not have any A, B, or RH antigens

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?

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 RBC's, and their blood serum does not contain antibodies against A, B, or Rh antigens

Blood type A- would give which of the following results?

agglutination with anti-A antibodies

Red blood cell membranes have

agglutinogens that specify that individual's blood type.

Which of the following terms can be used interchangeably?

antigen and agglutinogen

ABO and Rh agglutinogens

cause the most vigorous and potentially fatal transfusion reactions

Antibodies to the A and B antigens are

found preformed in the blood plasma.

Which blood sample contained the universal recipient?

sample 5

Which of the blood samples tested could donate to a person with type A+ blood?

samples 1 and 4

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.

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.

If the patients blood type is AB; what would be the appearance of the A,B, and Rh samples?

A, clumped B, clumped Rh, unclumped

Agglutination

All of these answers are correct

ABO and Rh antigens

All these answers are correct.

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

Anti-B antibody

Antigens

Are present on all cell surfaces

List the blood sample that represent people who could donate blood to a person with type B+ blood type

B+ (sample 2), B- (sample 6) O- (sample 4)
