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 |
