Typically, blood type tests are performed through addition of a blood sample to a solution containing antibodies corresponding to each antigen. The presence of an antigen on the surface of the blood cells is indicated by agglutination. Predict the blood groups in results P, Q, R and S:
| P | Q | R | S | |
| 1. | O positive | A negative | B positive | AB negative |
| 2. | O positive | A negative | B negative | AB positive |
| 3. | O negative | A positive | B negative | AB negative |
| 4. | O negative | A negative | B positive | AB positive |

What is true for the blood Type O?
| 1. | It is universal donor because it has neither anti-A antibodies nor anti-B antibodies circulating in the plasma. |
| 2. | It is universal donor because it has neither antigen A nor antigen B on its RBCs. |
| 3. | It is universal recipient because it has neither anti-A antibodies nor anti-B antibodies circulating in the plasma. |
| 4. | It is universal recipient because it has neither antigen A nor antigen B on its RBCs. |
