KROK 1 2016 – Question 98 · KROK (Medicine) · Physiology
Blood group of a 30-year-old man has been determined before a surgery. The blood was Rhesus-positive. Agglutination did not occur with standard 0 (I), A (II), and B (III) serums. The blood belongs to the following group:
- A. A (II)
- B. 0 (I)
- C. AB (IV)
- D. B (III)
- E. -
Hint
Remember that standard sera detect agglutinogens on the red cells, and consider what the complete absence of agglutination means for those antigens.
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.
