A pregnant woman had her blood group identified. Reaction of erythrocyte agglutination with standard serums of 0αβ (I), Bα (III) groups didn’t proceed with standard serum of Aβ (II) group. The blood group under examination is:
- A. Bα (III)
- B. Aβ (II)
- C. AB (IV)
- D. 0αβ (I)
- E. -
Hint
Recall which agglutinins each standard serum contains and which red-cell antigen would be clumped only by sera carrying the matching agglutinin.
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.
