ABO Blood Group System

What are the four main ABO blood groups?

• A-, B-, AB-, O-

• A1, B1, AB1, O1

• A+, B+, AB+, O+

• A, B, AB, O

Which antigen is present in blood group A?

• O antigen

• AB antigen

• B antigen

• A antigen

What is the significance of the Rh factor in blood typing?

• The Rh factor is crucial for determining blood compatibility in transfusions and preventing complications in pregnancy.

• The Rh factor has no impact on blood donation.

• The Rh factor is a type of blood cell that carries oxygen.

• The Rh factor is only relevant for organ transplants.

Describe the principle behind the agglutination test for blood typing.

• The agglutination test identifies blood type by detecting the presence of specific antigens on red blood cells through antibody binding.

• The agglutination test measures blood pressure to determine blood type.

• The agglutination test identifies blood type by analyzing plasma proteins.

• The agglutination test uses a microscope to visualize blood cell shapes.

What blood group is considered the universal donor?

• B negative

• O negative

• A positive

• AB positive

How can blood type be determined using enzyme-linked immunosorbent assay (ELISA)?

• Blood type can be established by counting red blood cells using ELISA.

• Blood type can be identified by analyzing DNA sequences with ELISA.

• Blood type can be determined by measuring blood viscosity using ELISA.

• Blood type can be determined by detecting the presence of A and B antigens using ELISA.

What is the role of antibodies in the ABO blood group system?

• Antibodies in the ABO blood group system are responsible for producing red blood cells.

• Antibodies in the ABO blood group system enhance blood clotting.

• Antibodies in the ABO blood group system transport oxygen in the blood.

• Antibodies in the ABO blood group system identify and react against incompatible blood types.

Explain the importance of blood typing before a transfusion.

• Blood typing has no effect on the success of a transfusion.

• Blood typing prevents serious immune reactions during transfusions.

• Blood typing is only necessary for organ transplants.

• Blood typing can be skipped if the donor is a close relative.
