Four Different Blood Group

Q.

Why is it necessary to know the blood groups before giving transfusion?

Q.

What are the following?

(a) Rh factor

(b) Universal donor

(c) Diapedesis

Q. The blood groups of both the donor and recipient must be known before transfusing blood. Give reason.​

Q.

Give scientific reasons for the following statement:

Blood group AB is called universal recipient.

Q. What are the different blood groups identified by the ABO blood grouping system?

Q. Match the blood group recipients with their possible blood donors.

1. AB blood group
2. A and O
3. B blood group
4. A blood group
5. B and O
6. AB, A, B and O

Q. Person with blood group AB is considered as universal recipient because he has

1. both A and B antigens on RBC but no antibodies in the plasma
2. no antigen on RBC and no antibody in the plasma
3. both A and B antibodies in the plasma
4. both A and B antigens in the plasma but no antibodies

Q. A drop of blood from a blood donor is mixed with serum from a group A person and serum from a group B person. The donor's red cells clumped in the A serum but not in the B serum. What is the donor's blood group?

1. A
2. B
3. C
4. D

Q. Match the following blood groups with the antibodies present in them.

Q.

When a person is said to have B positive blood group, what does the "positive" refer to?

1. Whether the Rh factor is present (positive) or absent (negative)

2. Whether the person has AIDS (positive) or not (negative)

3. That the person has received the B blood group from the mother

4. That the person has received the B blood group from the father

Q.

The blood group which is the universal acceptor is __(i) and the one that is universal donor is __(ii).

1. (i) AB, (ii) O

2. (i) O, (ii) AB

3. (i) O, (ii)A

4. (i)A, (ii)B

Q. The compatibility between the donor and the recipient is decided on the basis of

1. Blood group matching.
2. HLA matching.
3. Both A and B.
4. Rh factor matching.
