KROK 1 2015 – Question 174 · KROK (Medicine) · Physiology
Determining a patient’s blood group with monoclonal test-reagents revealed positive agglutination reaction to anti-A and anti-B reagents, and negative reaction to anti-D. What blood group does this patient have?
- A. I (0) Rh+
- B. II (A) Rh+
- C. IV (AB) Rh−
- D. IV (AB) Rh+
- E. III (B) Rh−
Hint
Read each reagent separately: agglutination shows that the matching antigen is on the red cells, and no agglutination shows that it is absent.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
