Q. No.A person with unknown blood group under ABO system, has suffered much blood loss in an accident and needs immediate blood transfusion. His one friend who has a valid cetificate of his own blood type, offers for blood donation without delay. What would have been the type of blood group of the donor friend?
| 1. | Type AB | 2. | Type O |
| 3. | Type A | 4. | Type B |
Different blood groups are due to:
| 1. | Specific antigens on the surface of WBCs |
| 2. | Specific antibodies on the surface of RBCs |
| 3. | Specific antigens on the surface of RBCs |
| 4. | Specific type of haemoglobin in RBCs |
When the plasma of a person has both anti A and anti B antibodies the blood group of this person would be:
1. A
2. B
3. AB
4. O
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. | Both A and B antibodies in the plasma |
| 3. | No antigen on RBC and antibody in the plasma |
| 4. | Both A and B antigens in the plasma but no antibodies. |
Choose the incorrect match with respect to blood component
| 1. | Leucocytes – 6000 - 8000 mm–3 |
| 2. | Globulins – Involved in defence mechanisms |
| 3. | O– blood group – Antibodies A and B absent |
| 4. | Thrombokinase – Converts prothrombin into thrombin |
ABO blood grouping is based on
| 1. | presence of two soluble antibodies |
| 2. | absence of two surface antigens |
| 3. | presence of two surface antigens |
| 4. | both (2) and (3) |
A person with AB blood group:
| 1. | Has A and B antigens in his plasma |
| 2. | Has antibodies on RBC surface |
| 3. | Can receive blood transfusion from a person of his own group. |
| 4. | Can donate blood to all other group recipients |
A person can receive blood only from a donor of his/her blood group if the blood group of this person is:
| 1. | O | 2. | AB |
| 3. | A or B | 4. | A, B, AB or O |
